I think Imma stand by my conjecture of an Ox cylinder going “missile” from a ruptured cap valve.
Further spec: Poorly secured and jostled during take-off/climb.
Given volatility of OX...there was likely a jet of fire behind it, engulfing the immediate interior.
At this time, it does not appear -to my eye- there was foul play.
Waiting on NTSB report.
