It sure seems that flight termination was very clean and deliberate. Two
clean explosions a few seconds apart. Is it possible that the loss of
several engines meant that altitude and velocity was not adequate to
satisfy successful flight parameters, the safety system would not allow
separation, but instead, demanded explosive termination of the booster and
the second stage flights? I dont think it was a rapid unanticipated
dissasembly- it seemed clean and clearly deliberate.
If the second stage had inadequate velocety and was separated and ignited,
it might have ended up .... anywhere? and that would not be good.
So success is impossible, get it over with with minimal threat to others.
