people going on about alternative theories - seriously ???
If they are saying that
a)the pilot was being kept out of the cockpit by manual controls inside the cockpit
b ) the copilot was inputting manually the controls multiple times to guide the plane down and
c) heard breathing
clearly the co pilot crashed the plane intentionally
I did like when the CEO of LH said something along the lines of " when you fly a plane into a mountain with 150 pax it isnt suicide, it is another word...... "
