What I was trying to say is the BOI will establish the chain of events, as to why the drogue appears to have failed to deploy is secondary to the main issue, true it has a bearing on a successful outcome, which this sadly wasn't, but the main concern surely must be as to why the seat and rocket (If it did) fired in the first place, you can speculate all you like but please remember members of the families involved may also be reading this thread.
And far from being a "thread Police" I simply prior to this linked the thread to the Condolence book out of a mark of respect to the poor guy.
