theories are just that - and guesswork is the same - just that..
my feeling is that this is just what the involved parties want officially - again - just my own guesswork..
only the people actually having the data in their possession will know the real facts and then it is up to them what they want to disclose to the public - to suit their agenda..
I sincerely want to believe we will get the real facts - in public - but apparently it has happened through the history of accidents that not all facts were disclosed..
