I don't think the pilot did it.
But if I were to go along with your theory that he committed suicide, then why didn't he just get airborne and turn into the Petronas Towers?
Hell of a statement. Randomly, there is a precedent for flying jets into buildings.
Seems fanciful that he wanted to kill himself and everyone on board, but to do it by flying around until he ran out of fuel.
All these busy calculations to work out where the aircraft is based on after running out of fuel...hardly the work of someone topping themselves....'I want to kill myself, but I want to stay alive as long as possible aka until there is no more fuel!'
So many holes in each theory, yet people seem adamant they know their ideas to be true.
