although much can be specullated after it appears Andreas L had depression back in 2009, i must say that suicidal thinking is not always linked to depression.after many years working as RPN, i can assure you about that.

however, after reading and hearing what french investigators have said, i can only assume that this was an well planned action, because, if the copilot was complete silent and did not utter a single word through the rapid descent, that suggests that he was very clear about what he was doing, did not hesitate one single moment.It indicates also he was not afraid at all and at the same time, he was very determinate in pursuing this absolutely shocking act.

I do not believe this was an impulsive act.Not one second.

Of course, my assumptions can be valid only if the homicid theory proves to be true.

I do not see this as a suicide, rather an homicide.
