Given the evidence anyone suggesting ulterior explanations is in fantasy land !
There is no way someone could of done the commands necessary without being in control of their actions...
Also from the Daily Mail:
"Police investigating the Germanwings crash said tonight they had made a 'significant discovery' at the home of pilot Andreas Lubitz, who deliberately ploughed the Airbus A320 into the French Alps.
Officers refused to reveal details of the potential breakthrough but said it was not a suicide note.
Speaking outside the flat on the outskirts of Dusseldorf, police said they had 'found something' that would now be taken for tests, adding it may be a 'clue' as to what happened to the doomed jet."
