Naked Science - Angry Skies

the wind a powerful invisible force it reshapes landscapes destroys buildings and wrecks lives in a single day a severe storm can cause over 10 billion dollars of damage and when violent winds ripped through a city they can kill dozens of people and seriously injure hundreds naked science looks at the deadliest winds on earth within massive carpet-bombing hurricanes and violent surgical-strike tornadoes we meet the people who risk their lives to warn us of the storms major damage at the airport Aarthi major damage Airport it's leveling tower buildings we discovered just how fast a wind a person can take and join the scientists in the front line to discover the latest weapons in the battle against these deadly winds we want to know what can we do when angry skies strike three Friday the 13th August 2004 Hurricane Charley is predicted to hit West Florida in eight hours hundreds of thousands of people shudder up their windows and one and a half million leave the area but one person heads in the wrong direction Mike Tyson 'el storm chaser he gets his highs from high winds he's filmed many hurricanes and tornadoes and he knows charlie is going to be big this is the storm he has waited for all his life yeah Tice took shelter near a gas station storm actually deepened very fast and became a category four hurricane and the winds were just unbelievable within ten minutes the gas station was no more Tice had achieved his ambition charli's winds reach speeds up to 145 miles per hour there has to be the loudest thing I've ever went through in my life holy cow the one to experience something like that firsthand since I was a little kid and I finally did Tice's footage is terrifying evidence of just how dangerous the wind can be Hurricane Charley left more than 25 people dead made tens of thousands homeless and caused up to 15 billion dollars of damage there is a simple law of weather the faster the wind blows the more dangerous it can be the winds in hurricane Charlie peaked at 145 miles per hour but is this the worst the winds can get one place to find out is here the wind on Mount Washington in New Hampshire exceeds hurricane speeds on over 100 days a year according to the Guinness Book of Records this is the world's windiest place the mountains Observatory is staffed by meteorologists year round the scientists make light of the mountains reputation they even serve up the world's windiest breakfast on this spring day the wind reaches 35 miles per hour only 1/4 the speed of Hurricane Charlie but the winds here can get much much stronger ken Rancourt is the director of research at Mount Washington observatory a big part of his job is measuring extremely fast wins we go from the calm summer winds of 5 or 10 miles an hour to the winter winds of peak gusts of a hundred and eighty hundred and ninety miles an hour but Rancourt has a long way to go to match the wind speed measured back in 1934 one thing Mount Washington is known for is the world record wind on a spring day a few meteorologists alone in a hut on the summit recorded one of the great moments in weather science a Nana na meter on the roof was linked to a sounding device inside the hut at 1:21 p.m. 12 it went wild the meteorologists on duty time the clicks and calculated the wind speed 1.75 one point four three one point four two one point two three it came to 231 miles per hour a gust they recorded in their log and which blew them away with astonishment 231 miles an hour will they believe it was our first thought this terrifying gust was nearly 100 miles per hour faster than the winds in Hurricane Charley it was the fastest wind ever measured by a weather station a record still held today on the scale of hurricane winds it would be at the top of the range a category five hurricane Charlie was devastating but it was only a category four to find out how strong a wind a human being can handle we've come to a wind tunnel at the University of Washington in Seattle Lubeck a man who is either brave or foolish has volunteered to be our guinea pig I've heard a lot of stories about how can't breathe so we'll see how it goes Beck should be nervous all he has for protection are a pair of goggles and a safety harness if he gets into trouble the fan can be cut off from a control room nearby and very strong right now it's like really pushing my feels like they got a really fast festival-goer look at at 74 miles an hour the wind reaches hurricane speeds at 80 miles an hour Beck can no longer stand unsupported without the safety harness he would be blown off his feet at 90 miles an hour Beck gives up he hasn't even reached a category two hurricane but Beck is determined to try again at high wind speeds small particles in the air can cause serious injuries Beck wears a crash helmet to protect his head and eyes at 96 miles per hour the wind reaches the speed of a category 2 hurricane fast enough to cause moderate damage to buildings at 111 miles per hour it becomes a category 3 the wind speeds Beck is now experiencing could destroy a mobile home then the signal about the 120 120 miles per hour this is the typical freefall speed of a skydiver 131 miles an hour Beck is now experiencing the force of a category 4 hurricane this is the wind speed of Hurricane Charley at 155 miles per hour the wind reaches the speed of a category 5 hurricane it's now fast enough to tear the roofs off houses and blow down most trees just keeping his position in this wind is taking all Beck's effort finally the wind peaks at an astonishing 161 miles per hour the pounding on his body is exhausting unable to take anymore he cuts the fan the result of our test shows that you could survive a category 5 hurricane as long as you wore protective clothing were tethered by a safety harness and weren't hit by flying debris in nature wind is a far more terrifying force it is at its most frightening when it strikes in the form of a tornado oh my god did you see that twisters are deadly unpredictable missile-firing monsters in our quest to discover what we can do to save ourselves when they descend from the angry skies naked science needs to know what sort of early warning we have when twisters strike next on naked science multiple tornado strikes oh yeah classic tornado in progress again and storm chasers running for their lives oh there's another one in front of us never trained a ranger the wind is an invisible enemy it destroys buildings Latin cities and takes lives so far on naked science we have looked at hurricanes giant storms that like slow-moving carpet bombers devastate vast areas of land but there is a wind that wreaks its destruction in a tightly focused surgical strike tornado winds are so violent that they destroy all normal measuring equipment how fast they blow baffled scientists for years to find out they have had to resort to some extreme measures in 1842 Elias Loomis a professor at Western Reserve College in Ohio notice that chickens caught in tornadoes had their feathers plucked out by the wind this spurred him into devising an experiment to find the wind speed that caused this he decided to recreate the conditions of a tornado using a cannon his idea was to fire a chicken into the air fast enough to remove its feathers simple ballistics would then allow him to calculate its speed he concluded that the chicken was blown through the air at a speed of 341 miles per hour to find out just how fast winds and tornadoes really are naked science traveled to Norman in Oklahoma in May research vehicles gather here ready for the tornado season we join up with one of the United States leading weather researchers professor Josh Wurman he hopes the data he and his team collect will improve the forecasting of tornadoes by understanding the tornado is better we can lead to better forecasts and if the forecasts can be made just 5 or 10 minutes better people have more time to get to shelter Worman uses Doppler radar to measure the speed of the winds inside tornadoes today a storm is forecast 150 miles north of here in southern Kansas so can women find us a twister and measured just how fast tornado winds really blow / can we go knowing the conditions likely to cause tornadoes helps women track them down when warm moist air exists under much cooler air thunderstorms can form if they form below strong winds near the jet stream they can start to spin and are called super cells when conditions are right these super cells can create tornados the challenge facing forecasters is that only one in five or six super cells breeds tornadoes which ones do depends on the amounts of moisture instability lift and wind shear in the atmosphere Worman and his team are now 30 miles away from the developing storm to get detailed information of the wind speeds inside a supercell and the tornadoes it spawns Worman has to get in close typically within a few miles of the tornado the team uses two trucks which like a pair of eyes enable them to study the storm in three dimensions just to the west of Attica southern Kansas the skies darken the storm has already produced a tornado there it is oh the two trucks raced to get ahead of the tornado to set up and take readings this one is small an f0 tornadoes are rated by the amount of damage they caused at the bottom of the scale and f0 will damage signs and trees toward the middle of the scale an f2 tornado will tear roofs off houses near the top of the scale an f4 tornado is devastating it will level a well-constructed house at the top of the scale is an f5 it can sweep away a building and hurl cars through the air just as Worman and the team draw alongside their tornado it starts to die what the radar indicates that another tornado is forming the storm has everything storm chasing is a game of cat and mouse swings ball off here right credit card yes and figure we're gonna do Doppler to the north side the Doppler radar sends out radio waves which reflect off drops of rain and other debris in the tornado by measuring the timing of the reflected waves the computer calculates the wind speed seen here at eight times normal speed the research camera captures the awesome side of the tornado developing this tornado appears to be at least an f2 the winds are strong enough to snap trees and tear the roof off a building sin to the debris Oh as the tornado passes through Attica it hits a house I'm gonna boy oh my god did you see that the whole house came apart the team hopes their research will give earlier warning times to help avoid such disasters Worman only has minutes to collect the data he needs from the tornado prey of new action to Arnie's Southie sorry south-southeast right here suddenly one of the teams spots another tornado forming we gotta go the race is on to get the trucks into position to survey the new storm to our east southeast all right keep an eye out they put their foot on the gas to get safely past the twister six 3.25 away our crossbar savvy oh yeah classic tornado in progress again oh there's another one in front of us we can safely go south think we should go in our bedroom sure where's doubt - now Wow and it's really close oh my god even though they are racing to avoid the twister they still want to collect their data Brown Ronin that's 134 miles per hour Worman stops the truck to start recording data immediately turns out watching this big dusty one die-off here the next tornado action could be right out here off to our East right now we're just scanning that always change the scan he's going back east this supercell thunderstorm is now spawning tornadoes at the rate of roughly one every 15 minutes look down here the tornado is just on just a crossing the road right now just on the other side as darkness descends the tornados become invisible to the naked eye this is a storm spotters nightmare the radar is the only way they can see the unpredictable monsters spawning around them hey Josh what what's coming up behind us intensity is work aging at least wind speed wide tree on the borderline between f2 and f3 it's an f3 intensity Oh mom what's that out there okay this is the big deal oh my god we definitely saw some ground relative wind speeds around 80 meters per second that's 179 miles per hour still up there yeah 85 meters per second last week 94 is 93 is f/4 that's 3.6 kilometers for a North East so it's getting stronger you think you had peak surface winds over 100 judge does believe peak surface winds are were or and are are in excess of 100 meters per second that's more than 220 miles per hour in the darkness a devastating f4 tornado is tearing across fields less than two miles destroying the farmstead you might want to call the Weather Service office this tornado is definitely in a very strong category now it's time to get out of the area fast the tornado is causing damage but luckily no one has been killed at midnight the team rendezvous in a coffee shop the supercell storms today produced about a dozen tornadoes some of them with extremely violent winds one of the tornadoes had winds well over 200 miles an hour it was a f4 strength tornado at least wormans team recorded winds today of around 221 miles per hour but this is well short of his record a few years earlier he logged the fastest tornado winds ever recorded on May 3rd 1999 a giant storm descended on Oklahoma City we measured wind speeds as high as 301 miles an hour the 301 miles now represents the highest that's ever been measured and clearly a devastating wind speed for any kind of normal home structure some sixty tornadoes were recorded in Oklahoma that day the winds killed over 35 people and the damage was estimated at over 1 billion dollars next up on naked science we meet the people in the front line of tornado defense and see what happens when an f5 twister strikes a major city our total devastation so far our naked science we've seen that tornado winds can reach speeds of over 300 miles per hour most twisters hit the countryside there's so much of it but just occasionally one strikes a major city when that happens we want to know what is our front line of defense to keep people out of harm's way Oklahoma May 3rd 1999 before the day is out some 60 tornadoes hit the state killing over 35 people jeff Petrowski is a highly regarded storm chaser he witnessed the first tornado touchdown it was very fast that day it started rotating and I called the first rotation in just north of Lawton within about 30 seconds later they had a tornado warning out and within about another minute it started producing a tornado it's coming a subdivision in the Oklahoma outbreak Petrowski played a vital role in saving lives I'm a ham radio operator so I was in constant communication with Norman Weather Service petrowski's call was picked up by the weather office in Norman they issued a tornado warning to the media and the public once you get that warning it's critical that you act very quickly because you may only have minutes or sometimes even seconds before the tornado strikes around the weather service quickly relayed the warning to local television stations the media then warned the public in the path of the tornado at Oklahoma City's channel nine meteorologist Gary England was shocked by the power of the storm yet below ground each time it's cycled so to speak it produced a larger tornado and a stronger tornado strike as the tornado plowed toward Oklahoma City Petrowski risked his life to track it he continued to radio its position to the weather service only spotters can tell us absolutely 100% for sure that we have a tornado occurring his turn major names to my Southwest I had the ham radio talking to Norman National Weather Service in constant communication of almost a play-by-play of what intersection what town was next who was in the path and what I was witnessing as the tornado was evolving and 29th and cedar I had total devastation right now Petrowski followed the tornado into the town of Moore he was now experiencing what seemed like the end of the world Brown was vibrating my van was literally shaking I can feel the vibration of my body I roll down the window everything on that block was gone there was factories building trees it was an industrial park area and as I looked north on that road everything was gone the next day the residents of Oklahoma City were left to pick up the pieces the tornado had tone a 19 mile path of destruction through the area thirty-six people had died some 700 were injured and over two thousand left homeless but if it hadn't been for the weather warnings more lives would have been lost in recognition of petrowski's skill in tracking the tornado and saving lives The Weather Service gave him an award I didn't realize I was going to film and witness the strongest tornado ever on the planet strong US winds ever measured on planet earth also the most destructive tornado in US history as far as dollar damage and literally two or three weeks later before I could actually cope with cutting back down and seeing all the destruction I actually stayed away from the damage error for about three weeks and didn't want to talk to anybody about it because it was so overwhelming Oklahoma showed that close liaison between spotters on the ground and meteorologists is one of the best weapons in the war against deadly winds we have thousands of storm spotters just here in our area alone really is the first line of defense against severe weather the winds in Oklahoma City that day reached over 300 miles an hour but the wind doesn't have to be that strong to create serious damage much slower winds can wreck buildings and fill the air with flying debris missiles that can kill in Lubbock at Texas Tech University researchers have brought in a c-130 Hercules to act as an outdoor wind machine they want to see how fast the wind has to be before it damages this building at 70 miles per hour shingles start flying off at 100 miles per hour part of the roof blows away now damage the house feeds the wind with a steady supply of flying objects once in the air the wind turns this debris into life-threatening projectiles when a tornado hits a populated area flying missiles caused most of the casualties next up on naked science we put you at the center of the Maelstrom we see what happens when missiles bombard a house and meet a woman who was hit by one and lived to tell the story this is the day after the 1999 Oklahoma City tornado people scour the ruins for survivors their task made more difficult by the acres of debris that covered the ground when a big tornado strikes it shoots out debris at such high speeds that even people who take refuge in their homes can be in mortal danger so how strong does a house have to be to withstand a tornado if Godzilla owned a BB gun it would look like this a 30 gallon tank of compressed air that can fire anything from bricks to steel posts at up to 100 miles an hour at Texas Tech wind research facility in Lubbock a group of researchers test house walls to see how well they stand up to flying debris they're testing what happens in winds you'll find in f3 to f5 tornadoes Chad Morris is the associate director of the wind Science & Engineering Research Center he's crusading for stronger walls to protect people from the debris thrown by tornadoes at 250 miles per hour those winds will move a piece of 15 pound debris at about 100 miles per hour so we're launching these the debris here today are the missiles at 100 miles per hour first up is a wall found in many US homes this particular target is a vinyl cladded wall section where we have vinyl sheathing an inner layer of OSB on a 2 by 4 stud system today's test missile is a regular plank of 2x4 a common projectile and tornadoes clear 2 1 over five million people live in houses built of this type of material in a strong tornado this wall might as well not be there next up is a wall found in nearly 8 million homes we have an exterior layer of brick veneer followed by interior layer of sheathing attached to a 2 by 4 stud wall system what although this wall slows down the missile you could still end up in the hospital however if you really want to protect yourself from tornadoes you need a storm shelter built of this you have approximately three-and-a-half to four inches of 3,000 psi or greater concrete with number four or half-inch rebar this gives us the mass that we need to be able to stop the missile as traveling at 100 miles an hour clear three two one one when the big bad wolf comes a-blowing this will do the trick but what happens if you don't have this protection and a tornado comes your way Julie rake straw lives in Moore Oklahoma in May 1999 she heard the tornado warnings and took shelter with her daughter in a closet in the middle of her house I was sitting in the closet and then all of a sudden I was looking down the street and seeing I'm thinking yeah this is not good one of the tornadoes to hit Oklahoma that day had destroyed Julie's home moreover it drove this piece of wood into her head I didn't know that there was a board in my head and the paramedic when he first we were friends and first thing he said when he came up to me is nearly as bad when the paramedic says something like that the paramedic used bandages to stabilize the board and then rush Julie to the hospital dr. Chris Kerry was one of the surgeons who treated Julie we were trained also not to be shocked by things going on but did take me aside a little bit to look at that the medical team became carpenters first part was actually to cut this big piece hanging out outside away from that so basically cut off the skin we didn't have any tensile do that and so we kind of improvised by sterilizing a saw that the maintenance people had to cut that off of that stage it went through my ear through my throat and into my collarbone and luckily that board actually saved my life because if it had gone all the way through and the best of through my collarbone I would have bled to death Julie rake straw had been hit by a three-foot piece of wood that had penetrated 20 feet into the center of her house but Timbers like these weren't the only type of missile flying around that day well the most common injury we saw in this tornado was just a strap nail injury almost like a blast type injury the sheer wind force generated so much energy that you know straw goes to trees in tornadoes everyday objects that we take for granted become killers at the national severe storms laboratory in Norman Oklahoma meteorologist Harold Brooks studies tornadoes and how they kill the biggest thing it kills most people in tornadoes is is blunt force trauma getting hit by the debris even ordinary objects flying at 150 or 200 miles an hour become compelling missiles if you're hit by them at 250 miles per hour the wind will propel a 15 pound piece of debris the weight of an average Thanksgiving turkey at about a hundred miles per hour people who survive tornadoes frequently get very very devastating injuries to them they may lose fingers ears lots of really awful soft tissue injuries and the kinds of things that take years to recover from fully Lee rake straw isn't going to be caught out twice when she rebuilds her house she made sure it included a tornado shelter this is our underground storm shelter we don't have to worry about getting hit in the head anymore I have you know first aid kids watering just in case that we're gonna be down there for a little bit storm shelters probably save the lives of hundreds of people each year but many people don't have them tornadoes kill about three times as many people as hurricanes this is the nation's most deadly wind we've seen that the winds inside tornadoes are much faster than the winds inside hurricanes this should make them more destructive but which wind actually causes the most damage when tornadoes hit cities the damage they do is phenomenal but as this bird's eye view of a tornado path shows the width of the destruction is limited in contrast hurricanes are vast typically 300 miles across this sheer size makes them much more devastating while tornadoes are the high-speed drills of the weather world hurricanes are the power sweepers they spread their destruction far and wide and the power within them is extraordinary a moderately sized hurricane can release as much energy in a day as 400 hydrogen bombs naked science wants to find out if there is anything we can do to prevent so much damage when the next hurricane strikes hurricanes there wins maybe only around half the speed of those in tornadoes but the destruction they cause is on a much much bigger scale here at the National Hurricane Center in Miami meteorologists forecast when and where hurricanes will strike the advantage hurricane forecasters have over there tornado colleagues is that they have longer warning times and each year it seems the forecasts get better a fact that Florida International University's professor Hugh Willoughby is proud of we've been able to reduce the risk to life chances of dying in a hurricane have decreased by a factor of a hundred in the course of the 20th century the hurricane center's track forecast accuracy improves on average by one to two percent a year one or two percent a year doesn't sound like much but over 30 years it adds up but there's an element of hurricane forecasting that is extremely difficult predicting just how strong a hurricane will be when it hits land the sand is hitting us so hard the most destructive hurricane of recent years occurred in 1992 on Sunday August 16th satellite pictures showed a tropical depression forming in the eastern Atlantic by the time the disturbance reached Florida it had grown into a powerful storm and had been given a name Andrew but just before it hit land the forecasters underestimated its strength stanley Goldenberg is a hurricane researcher if anyone could have seen what was coming it was him but his Hurricane Andrew approached Miami Goldenberg put himself and his family in just about the worst possible place calmly waiting for hurricane Anne through his home was directly in the path of the storm and protected only by plywood shutters here that outside I woke everybody up and said well this is the time we got to start what we call hunkering down in the hallway and we got some mattresses and sheets to protect against flying the last winds outside I think or at least a hundred hundred and ten miles an hour or more Aaron are you okay and there's the cat Goldenberg relied on plywood and God just waiting out of the hall because we lost the plywood on the front window but we are praying God will cover that when the eyewall hit it was like someone took a gear on a gearbox and just revved it right up Lord we just thank you we yes your protection beautifully in an explosive smash when that window went and then blew out the sliding glass door in the back so we had a hurricane just roaring not too many feet from us through the house and and then at a certain point my brother-in-law said he said the roof was gone indeed the roof had lifted off in one piece and flew over the fence and smashed into the neighbor's house the living room kitchen wall fell on us it propped itself up by the refrigerator by about one foot so it made like a little hiding place for us but is sad to say this stove was on my back it felt like my knees were being crushed and we were just praying cry out to God just hoping for this thing to let up Goldenberg and his family survived it was only when daylight arrived that he realized the full scale of the damage you can now see this is the wall fell on top of us stove down their cabinets these shutters survived the storm every window covered with this type of shutters survived but our house which had wood shutters the roof lifts it off the roof lifted off Hurricane Andrew devastated a total of over 1,000 square miles of land the Andrew hit the least populated section of miami-dade County if it had been just 20 miles to the north all the statistics would have been almost tripled Andrew left around 160,000 residents homeless and killed 23 people it taught scientists never to underestimate the power and unpredictability of wind all in all it went from a minimal tropical storm to a category 4 than category 5 hurricane in just about 36 hours a tremendous tremendous intensification which is the hardest thing for us to forecast as these rapid intensification Hurricane Andrew caused more than 20 times as much damage as the United States worst tornado when averages are taken into consideration year after year hurricanes caused nearly five times as much damage as tornadoes but do hurricanes have to cause so much devastation is there any way we can prevent the wind being so destructive we know that the damage caused by a hurricane goes up dramatically with wind speed in some conditions reducing the wind speed by just 10% can reduce the damage by a quarter the powerhouse of hurricanes is the moisture within them as water vapor condenses it releases enormous quantities of heat that helps to drive the storm remove some of the moisture and in theory you weaken the storm that's exactly what scientists tried to do in the 1960s project Stormfury assembles a team of highly trained scientists and technicians in 1961 the US government funded project Stormfury the plan was to seed hurricane clouds with silver iodide particles these would convert supercooled water in the clouds into rain and caused the eyewall the part of the hurricane with the fastest winds to break down tests on hurricane Debbie in 1969 appeared to succeed in reducing wind speeds by an average of 25 percent but the subsequent research revealed that most of this dramatic reduction probably wasn't caused by the seeding but by a natural storm cycle and would have happened anyway after more than two decades project Stormfury was finally abandoned in Palm Beach Florida businessman Peter cordon II believes he can succeed where Stormfury failed he has created an absorbent powder that he says will one day reduce the power of hurricanes to polymer-based product it has the capability to absorb 2,000 times its own weight instantly so you'll see when I dump it in the water here it will absorb all that moisture instantly just a little bit you can see how it's absorbing it right now so our whole theory is if we could absorb the moisture it will take the devastating punch out of the storm in 2001 Peter core Donny's team tested the powder on a storm cloud this thing was building it was abrupt and it was perfect fall and we released the load on it it absorbed all the moisture and dropped that storm out of the atmosphere instantly a foster to the ocean it was like magic who was on the radar it was gone off the radar independent observers confirmed that the cloud disappeared but wiping out a cloud doesn't mean the powder can weaken a hurricane the scale of the problem is so much greater even though core Donny's work continues weather experts doubt the likelihood of success scientists believe that the best way to prevent hurricane damage is to improve building design and make more accurate forecasts so that areas in danger can be evacuated as slow-moving events that build up gradually oversea hurricanes are spotted several days before they hit land and there is usually plenty of time to give people warning by moving people away from the danger zone many lives are saved in the United States only about 20 people are killed each year so far the forecasters are winning the war against hurricanes but things may be about to change when Hurricane Charley hit Florida in August 2004 it seemed forecasters were on top of it the National Hurricane Center issued a warning for most of the West Coast one and a half million people evacuated the area others took shelter but despite the warnings more than 25 people lost their lives Charlie was a category 4 hurricane a whole category below Andrew but it killed more people so what went wrong bryan norcross has been predicting the weather in miami for twenty years he's seen hurricanes come and go and he believes there's an extra dimension that hasn't been factored in I think we're losing the hurricane battle overall the amount of building that's right at the coastline therefore the number of people that are piled at the coast is exceeding our ability to warn and even if we could warn perfectly a certain percentage of people are not going to react until the last minute anyway since the 1950s the number of people living on the East Coast of the United States has almost doubled and however strong the warnings there will always be some who won't leave until the last moment so we know that a significant number of people will be left in harm's way when a hurricane come massive carpet-bombing hurricanes and violent surgical-strike tornadoes are among the most terrifying forces on earth the intense speed of the air and a tornadoes towering vortex makes it the deadliest of all winds and the awesome size of a hurricane ensures it is the most destructive science has sought to understand and protect us from these whirling monsters improved forecasts and longer warning times we'll continue to save lives but they will probably never be 100% accurate what angry skies strike the only thing to do is get out of the way you you
