stainless steel - cheaper, heat resistant, and more easily assembled two instead of three fins SpaceX history Bob Wilson
Thanks Bob, but no way am I going to watch an hour-and-23-minute video of Elon going on and on about the history of SpaceX with, probably, just a few minutes of talk about stuff he hasn't said before. At least, that's the usual type of publicity even that SpaceX and Tesla do. Fortunately, The Atlantic has an article that seems to provide pretty good coverage: "SpaceX Has Starry-Eyed Ambitions for Its Starship" I can't figure out how it's supposed to land, when returning to earth, on just two tail fins. Unless I'm missing something, it needs at least 3 to be stable. Maybe it's two fins plus a couple of extensible landing legs?
