I agree with most of it and have a couple of points:
Rothschild says:
And, as Debunking 9/11 Myths notes, "a Cleveland air traffic controller assigned to Flight 93 heard signs of a struggle in the cockpit, followed shortly by screaming."
Actually, I think this must refer to the hijack (which Cleveland heard), not the crash (the audio of which was later obtained from the CVR). If PM really made this mistake (i.e. it's not just an error by Rothschild), then it won't look good for them.
Re Almihdhar there are a couple of points that could be added:
(a) I have six sources that say the NSA was listening to Al Mihdhar's calls from the US to Yemen, including the DOJ's Office of Inspector General and FBI agent Dan Coleman who, after 9/11, read the dispacthes the NSA drafted about (some of?) the calls. In addition, there was an operation (perhaps called Catcher's Mitt) monitoring Al Qaeda operatives in the US before 9/11 - the Joint Inquiry confirmed the NSA was still picking up Al Qaeda intercepts from the US in 2001;
(b) The CIA admit openly they were following Al Mihdhar and the Al Hazmi brothers around Malaysia and this was a big operation. The CIA says they lost him, but according to KSM, Al Mihdhar thought they were followed to LA;
(c) Rumsfeld was told on 9/11 that three of the American 77 hijackers had been followed "since Millenium and Cole";

You could also have thrown in:
(e) The surveillance of the Hamburg cell;
(f) The other hijackers known to intelligence agencies. In total I count 11 hijackers that were known to intelligence agencies before 9/11, although not all of them were as well known as Al Mihdhar.
The idea is right though, when people like Rothschild bring up no-planeism, we should hit back with the hijackers. The argument the CIA and NSA know more than they are telling is absolutely stone-cold nailed-on.
