@antlerboy The 4/20 stuff is overblown... at SpaceX they have always been cowboys. The launch had been in the works for months, and nobody ever knows the exact date for sure, especially with an experimental vehicle.
Yes, of all their bets skimping on the pad was one of the worst, and most criticized. It will cost them, but it won't fundamentally change matters.
@antlerboy NASA doesn't think so. Only time will tell.
@werner58 heavy rocket still a fundamentally bad idea?
