According to CNN, the transponder was only turned off on 1 of the
planes; the United flight that crashed outside of pitt.

The transponders, like most avionics, has a handy-dandy off switch.

Somehow the people who did this managed to turn off the transponders
on these planes. Normally a plane flying in controlled airspace
squawks a unique id and altitude which is decoded by their radar and
associated with each blip. Sometimes low cost homebuilts/ultralights
fly with no transponder, but Boeings <sarcasm>usually</sarcasm> do.
If you set a transponder to 7500, it means you're being hijacked.
BTW if you see your friend Jack at the airport, be sure to say,
"What's up, Jack!" instead of "Hi Jack!"
So how do you deal with this? Blowing up a whole country? I wonder
if the US should adopt a 'fire w/ fire' approach and invest in
intelligence, covert ops and assassinations. It would seem that it
is open season on terrorism by every democratic nation, I expect to
see very conspicuous Samuel Jackson style ass whoopins on whiny
extremist groups to satiate America's anger. Terrorize the
terrorists.
Oh yeah, obviously Echelon should probably have MacOS loaded on it.
