The combination of false radar blips due to wargame exercises combined with the turned off transponder enabled the perpetrators to switch Flight 77 with another plane. Perhaps Flight 77 landed in an empty hanger. The passengers were either gassed or shot with machine guns.
Whether it was thermite or not, it was something that caused all those explosions which brought down those towers. The impacts of the planes and the subsequent oxygen-starved fires did not do it. Something else did and we are trying to find out what it was. Bear in mind, truthseekers, the U.S. defense department undoubtedly has weapons and methods we have never even heard of. So it might not have been thermite. I don't think we should get too hung up on that though. The point is that the official fable is a scam and a BIG LIE.
If we truly had plane swaps (which I believe we did) and some of the original flights continued on - such as the phantom radar tracks suggests for Flight 77 out west - then the "all flights land ASAP at any available base" certainly provided perfect cover for that.
Skpetics would argue that a 757 flying rogue across the U.S. would draw air traffic controller attention, but I think we can assume that once the "mandatory landing" order went out and every airborne plane had to ditch, there was no way all flights would be monitored as to where they came from or where they landed. They would have their hands full just organizing the air traffic around airports. And with all that going on, no one would worry about any planes making unusual maneuvers or devating from flight plans, it was probably close to total mayhem.
It's the perfect cover, because it serves the purpose to allow the disposal of evidence, plus it make sense from a standpoint of what could be seen as "normal emergency procedure." Just like Cheney's wargames were cover for the alleged hijackings, the flight grounding order may have covered up the real Flight 77's removal.
