"I too want to know just how many Americans HAVE hijacked airplanes."

Hijackings are really, really rare events, but US Citizens have hijacked planes. One happened right here in CA a few years ago. A disgruntled airline employee hijacked a commuter plane, killed the cockpit crew and crashed the plane, killing everyone on board. You don't remember that happening?

The last hijacking in the US was 9/11. None since then.

I just ran a Google on 'hijacked +commuter' and got no reference to a California hijacking. If one has happened, perhaps you could provide a link to the story/

Oddly, a casual inspection of the google output (from above) shows scads of hijacked commuter buses and commuter trains.
