A lot of people also don't know that the 911 attack on the Pentagon was a direct hit on the offices of the accountants and budget analysts at who were investigating that missing $2.3 trillion.

So, for those offices to have been so precisely targetted, it pretty much rules out any possibility they were hit by an aircraft under manual control and when you look at the manouvre the aircraft made as it approached the Pentagon with a looping descent that ended with it skimming the ground at 530mph and taking out lightpoles, either the plane was on autopilot and it was homing in on a runway beacon planted at the Pentagon or it was a cruise missile. As the two planes that hit the WTC towers were also very precisely targetted, I think the runway beacon is the most likely thing.

So bearing that in mind, shortly after 911, Joe Vialls described a 1980's project to retrofit all American airliners with a system codenamed "Home Run" that was developed by DARPA in response to 1970s aircraft hijackings. That system allowed ground controllers to take control of a hijacked plane remotely, to lock the pilots out of the aircraft's control systems and to program the plane's autopilot to bring it to land at a chosen location.

Joe Vialls site was long since removed but it still remains in the archives and as you can see from this page originally dated October 2001, he was one of the first to start questioning the official narrative.

So anyway when you put all that together it can explain everything that happened on 911.

Firstly there could not have been any Al-Qaeda pilots flying planes into buildings because if there had been, the Home Run system would have been used to take control of the planes before they could have done that. That leaves only one credible explanation. The planes were under remote control by agents of the US Government who were using the very system that was designed to protect against hijackings to turn the aircraft into remotely controlled guided missiles and they had set up runway transponders at the WTC and at the Pentagon to guide the planes in precisely to their targets. If you look carefully at 911 pictures of the Pentagon there was something on fire outside the building directly in front of the impact site.

That picture was taken before the impacted part of building had collapsed. The actual impact point is at ground level amongst all that white foam but you can see there was something there in front of it on fire with a fence around it and you can see where part of the plane tore through that fence (perhaps one of the engines?). I'd bet that fire was where they had a mobile runway transponder set up directly in front of the offices of the accountants and budget analysts.
