We are assuming many things with that bit of info, however.
They immediately report that the “breathing was normal” and, ipso facto, he was perfectly healthy. Nonsense. LOTS of medical things happen and still one can breathe normally, untinterrupted.
This assumes there is no way to accidentally hit a switch. However, unless it was placed in the optional position, the switch is located by the throttles, easy for a body or just a dangling hand to hit - and it is only a 1-position switch, to boot (not 3, which I would think would be better).
Furthermore, looking at the emergency-door video on this plane, they seem to say that there is a special code for outsiders to override ANY locking situation. How about that? (I may have misunderstood this part of the film, but I think that’s what was meant. They showed both crewmen passed out as a possibility, with the door “locked”, but the stewardess punched in a special code to get it open.)
So, again, I want ALL info out and that takes more than 1 day. Air investigations always take much longer than 2 days. Analysis takes much longer. None of this would stand up in court.
It is just plain totally irresponsible of the French authorities to mouth off within 24 hours as if they know so much. Nonsense.
I believe they are able to conclude firmly that the only way Lubitz could have denied the pilot entry was by deliberate choice, if it were possible he became incapacitated and inadvertently did so, I believe they would not have announced his deliberate choice to crash the plane. That is, to take your position assumes more, unrealistically more apparently, than the other way around, which seems to me to be a deducible fact.
