The 767 has a lovely navigation suite. One simply punches in the GPS coordinates desired (not hard to obtain--simply stand on the WTC observation platform with a GPS receiver and store the data), engages the navigation system, and the plane either (a) tells you where to steer or (b) if you're in a lazy mood, it will fly there itself on automatic pilot with altitude hold engaged.

Once in visual range, simply turn off the autopilot and steer the damn plane. Not terribly difficult.

This "report" improperly describes equipment (the description of the AWACS is a particularly funny one for those who actually know how these sorts of things work), jumps to conclusions not supported by the data, and generally multiplies entities beyond necessity.

Perzackly. BTW, wasn't Atta spotted loitering around the towers a day or so before?

More generally, this is one of the looniest theories I've seen in a while.

Remember the hand held GPS reciever that was found in some Arab's apartment in NYC? First the guy said he never saw it before, then he said it was his...then he said it must belong to his buddy....and that mentally challenged judge let him walk.
