Hildebrandt was sentenced to three years in jail for attempted murder, 10 years for attempting to destroy the aircraft and two years for the explosives charge. He successfully appealed the sentence in the Queensland Criminal Court as he argued that the aircraft which was 35 minutes into the flight, was over New South Wales (NSW) when he armed the explosives in the aircraft toilet. He served a three-year sentence in Brisbane, for attempted murder and on discharge was arrested by detectives from NSW. He faced court again and was convicted on the charge of attempted destruction of an aircraft and sentenced to seven years imprisonment in NSW.

So these were basically all state-level charges, it didn’t trigger a higher national-level charge?

Something that never made sense to me about 9/11 is how did the hijackers succeed against 200+ people while armed with some box cutters?
