Several interesting questions came to mind though, especially given the successful test of the Dragon 2's thrusters, which is whether or not an inflight abort could have saved the cargo. I understand that isn't practical in the general case but in the specific case of a Dragon cargo capsule, I'm wondering if they can fly one with the super draco thrusters. And have that one do the in flight abort sequence at some point in the future.
And given a rocket at mach 1+ what is the velocity of the explosion wavefront? In particular if you know that the back end of the rocket has just exploded, how many milliseconds do you have before the shockwave catches up to the front of the rocket? Could you perform a disconnect and burn of the super draco package to put the Dragon capsule far enough ahead of the shock wave to survive it?
