Please stop speculating. Nobody has been confirmed dead yet, and we have no idea what happened so cannot say that anything that has or has not happened is avoidable and unnessary.
I understand the desire to try to guess what has happened here and I am not suggesting that what anybody is saying is unlikely, but there are very few facts and very many unknowns at this stage. Difficult though it is, the only real thing to do now is sit tight and wait for actual news rather than second-guessing as the latter helps nobody.
