Yeah. A "black box" has been certainly recovered with sure lots of information that might have been as well streamed to the ground where they would have been monitoring all kind of values, as well as many cameras. I think a total of 6 cameras were on-board the vehicle, including some of them recording the cockpit, plus many other filming from the ground. As you said, this was a test flight, hundreds of times more monitored and recorded than any other kind of flight. I'm sure the people involved have already seen the accident from more than a dozen points of view, but it's difficult that those videos are ever going to be released to the the public.
Aye, it'll be *extensively* documented. But it will still take alot of time to work out exactly what happened.
