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.
It’s not unreasonable for him to have done it.
But, I am totally unconvinced they could come up with that “conclusion” based on less than a day’s “analysis”.
Coupled with the low probability of anyone just deciding to carelessly take others with them in their suicide (if not Moslem), or the low probability he was a Moslem, especially actually part of a “cell”, I just don’t buy it yet.
I’ll like it more if that remains after several weeks.
