Crackpot conspiracy theories are entertaining sometimes, its incredible the crap ignorant people can make themselves believe.
I came up with a pretty decent one myself, stating that not only are the moon landings fake, but all space travel ever, is a big hoax. Satellite communications are advanced HAM radio broadcasts, GPS is simple radio triangulation, the space shuttle blasted off (at an obvious arc) and landed in facilities in Europe (Moron and Zaragoza, Spain) without ever leaving the atmosphere. NASA TV is computer generated blue-screen stuff. All all the technology attributed to space flight is mirrored by the advances in computers, but use existing technology.
Also, space flight is impossible anyways, because nothing we've invented can go faster then Earth's escape velocity (11.2 km/s or 25,053 MPH, or 32 times the speed of sound) and satellites would be useless anyways because radio transmissions cannot escape the earth's ionosphere, they simply bounce off, except at a tiny point at the transmitter's zenith, which would tie every satellite to a geosynchronous orbit directly above a ground station and what would be the point when HAM radio can do the same thing?!!!1??/
Its all a plot to put taxpayer money into the pockets of the elite and keep you enslaved, man. / Its a plot by the UN to secularize the world and try to replace Jesus with hoax science.
