Watched videos and some space-related YouTube videos on this while eating lunch. That was clearly an explosion that based on the last frames of the available video shows the capsule and stand totally destroyed. Not sure why this is such a secret. Accidents happen and there is a lot of trial-and-error underway. Idiocy to expect perfection. This was a test for that reason. The real failure is the jump to secrecy, which undermines SpaceX and NASA credibility.
“Accidents happen and there is a lot of trial-and-error underway”
Yep. Rocket scientists keep blowing shit up until something eventually flies ...
