The pilot had a similar route to the one flown by MH370 on his home flight simulator according to the ATSB report. From Reuters:
"Six weeks before the aircraft’s disappearance, Captain Zaharie Ahmad Shah used his home simulator to fly a route that was initially similar to part of the route flown by MH370 up the Strait of Malacca, with a left-hand turn and track into the southern Indian Ocean, the ATSB said in its report."
It's highly likely that MH370 was the result of pilot suicide.
Indeed. Pilot suicide is just one theory and is not proven fact. Almost everyone thinks there was a decompression event on the aircraft. Another possibility is hypoxia causing pilot impairment as a result of decompression. Hypoxia severely inhibits brain function and turns you into an incompetent. It's similar to being extremely drunk or high on drugs. This happened on the Greek Helios flight that decompressed. The pilots can be heard on the recording becoming gradually unable to competently fly the plane and making ridiculous decisions due to brain impairment.
Well yes. Just to point out that list may be somewhat shorter that it looks as including 9/11 is somewhat of a technicality and it includes incidents that investigators think may be suicide but it remains unproven.
That list does actually mention MH370 as a possible suicide, which would be the correct way to describe it. It also states that several other theories have been offered. That's the point. The internet armchair crash investigators seems to think it was definitely suicide. Some TV commentators think it may have been suicide. However there are other valid possibilities and we just don't know.
If you want to hear about alternatives there's a good book by Christine Negroni called The Crash Detectives that goes through it in some detail including the hypoxia possibility as well as the suicide line of thinking and the pros and cons of each theory.
