Just after the pressure event you see Dragon being slung off the rocket... If only it was possible to deploy the parachutes during launch we could've hypothetically saved the payload. I wonder if the launch abort mechanism on the Dragon V2 would've been of any help here too to jettison it safely away from the rocket. I read the rocket was around maximum dynamic pressure during the event (Or just after?) and I'm not sure if it would stand such forces of a jettison during such time. |

The other meme is there are or have been rockets or overall systems with flight profiles and designs that have unsurvivable portions of the flight. Or only extremely theoretically survivable. Think of the old shuttle system, for example. A RTLS abort was theoretically survivable, but lets be realistic here... However the space-x guys are extremely proud that they designed an overall system that has no unsurvivable by design flight portions, and also very proud that they did a test flight with a separation near max-q specifically to prove it would work just fine even at max-q...
One interesting problem with a structural failure at that speed is it could be hard computationally to tell the difference between some irrelevant pogo-ing or vibration vs 50 ms later half the rocket is flying sideways, at which point it might be unsurvivable. Bad car analogy is I can jump out of an airplane with a parachute at 100 MPH and all turns out just fine, but randomly getting tossed out of a 100 MPH car isn't going to likely end very well even if under ideal conditions its no big deal.
