Hmmm. No mention of September 11, 2001.
I would have thought those plane crashes would have made the list, given

No, because those crashes were not unintentional. There was no failure
of technology or pilot error involved.


How did they get control of the aircraft if the pilots didn't error in
letting them into the cockpit?

Simple - there was no requirement to lock the door and the door wasn't
reinforced to prevent intrusion, until after this date.
