Now we're only left with stuff that has already been tested on COTS-1!

If it didn't separate on a manned flight, they might be able to do an abort burn to raise the perigee back up to give them time to troubleshoot and fix. That would likely imply having to do a water landing though, because they would have burned more propellant on the abort back to orbit, and the second deorbit burn.

(my guesstimate for a minimal orbit + another deorbit burn)I think you just have to accept that failure to separate trunk is a LOC event. Unless it is just hanging on by a thread, like what has happened on at least one Soyuz flight. I'm not sure Dragon has the same margin as Soyuz to handle such a thing, though.
SpaceX During today's descent, dual drogue parachutes will deploy at 45,000 feet to stabilize and slow #Dragon.I thought Dragon used 3 parachutes?
If crewed Dragon had to do a water landing, would they use the SuperDracos, or just go with chutes?
