I think it was becuse they hated the US or it was to commit suicide
The belief of the terrorists who crashed the planes into the twin towers was that the US has been interfering in the affairs of other nations for too long, and needed to be taught a lesson that other nations do not like what the US is doing and are not going to stand for it.
The people who crashed the planes into the World Trade Center had a great hatred for the United States and for Western society in general. The Twin Towers were a symbol of American prosperity, which made them a high-profile target. The towers had also been bombed eight years earlier in an attack financed by the same man who planned the hijacking: Kahlid Sheikh Mohammed.

at least 19 hijackers were in the plane that crashed the twin towers
To be honest no one knows the answer to that the planes had the pilots and hijackers and remember the hijackers were in the cockpit with the pilots but no one truly knows who was flying when they hit.
