No joke I've seen it, it was on Australian TV over Christmas.
It takes video footage from the pentagon and asks where the wreckage of an airliner went because there's no engines/metal/luggage etc etc visible at the crash site. It also shows some of the early video footage before the outer wall fell down and I must admit it looks more like a missile attack but I'm sceptical as to how selective the footage is.
It also claims that the owner of the towers filed to have them demolished and that the way in which the towers fall down is too similar to a planned demolition to be coincidence. It goes on to say that the 5th building that was imploded later in the day on 9/11 for safety reasons should have taken 8 weeks to plan and execute yet it was done in 8 hours.
There's about 45 minutes of the presenter trying to convince the audience that the planes that hit the towers had missiles hung under their fuselage based on low-res zoomed in poor quality video footage which was a bit tenuous. It's an interesting theory but I think that's all it is.
