That happened with an Egyptian airlines in I believe 1999, the Pilot wanted to off himself so he plunged the plane into the sea
actually i believe he chanted muslim prayers right before it happened....i believe a similar thing happened with a japanese or asian airliner 10+ years ago- the pilot purposely slammed the plane into the side of the mountain....they later said he was mentally ill- ya think?
And you believed that story?
The Egypt Air crash cause was covered up.
