Re: First stage landing was... damp
I doubt they'd risk it for a Dragon 2 flight. They're on a time crunch there and I doubt NASA would like them using this booster and risking a failed test (RUDing the booster doesn't give valid results if it happens before MaxQ).
I also have my doubts they'll be able to reuse it in the first place. Musk was very sure of himself when he tweeted, but that's before they've seen the actual booster. That thing toppling into the water like that must have done some damage to the (top) interstage section.
