It's a pretty faint memory already but is it in this video where she compares rockets to airplanes. I'm interested in the carbon footprint and I thought I heard somewhere that one rocket launch is equal to a plane flight overseas or something. If someones watching it. It's a pretty cool vid

waits for summary pretty please, tell me if it's worth watching!

“You will be on a ship for two plus months” - [Regarding flights to Mars] Not much difference but that seems be down from the usual three month plus time they usually quote?

Thanks for sharing.

This is the first time I see BFS with 4 landing legs!. My guess is that this is one of the two design options for BFR legs that Musk mentioned at the Dear Moon event. (The other option being the chosen one - legs integrated into the two fins and an added fixed fin for a third leg.) I think Musk made a good choice. The fins look much better! My guess would be that both options added a comparable amount of weight to the vehicle.
