Last week's failed test of the SpaceX Dragon 2 capsule has been conspicuous for the absence of any comments from SpaceX or NASA about what went wrong. Until recently, all that was known was that, from several miles away, smoke was seen drifting from the launch pad.
It now appears that the failure was pretty catastrophic. The Dragon capsule's ejection rockets were to be tested. They're designed to pull the capsule clear of its launch rocket in the event of a malfunction, before the capsule parachutes to a safe landing with its occupants. This video, allegedly taken from one of the launch pad cameras, and seemingly copied by a smartphone filming a display screen, is said to show what happened. (Profanity alert - the onlookers use some fairly descriptive terms to show their dismay.)
Yeah . . . if I were an astronaut, I wouldn't be real comfortable at the thought of riding inside that capsule, with that escape system! Some redesign appears necessary.
