This general has a very good reputation. He was one of the officers run out under Clinton for being too much of a straight shooter. I believe absolutely that plane could be in Pakistan, and I would trust this guy as much, if not more than, most others.
One thing is pretty certain about that plane.......if it did crash in the ocean, PARTS and PIECES from it would have washed up on shores, and nothing has been reported. It either LANDED or crashed onto an island or forest or mountain.
