What the Hoaxers forget to mention is that given the tech of the 1960s, it would have taken almost as much effort to fake the as it did to actually get there.
Probably significantly more.
About ten years ago the sci.space.history newsgroup tried to determine the minimum possible size of conspiracy needed to pull off a Moon landing fake (they were fairly sick of all the Hoaxers and decided to see if - with all their expertise - they could possibly determine a feasible faking). They couldn't get it below triple figures.
Bearing in mind that the launcher is visible in public (and indeed televised), its approximate capacity can be calculated from the fuel used or at least given a range). So the fakers would need to actually design and build a launcher capable of sending a manned mission to the Moon.
They'd also need to simulate a manned capsule and lander, so let contracts and have them do believable jobs (they can be checked up on). You'd also need the infrastructure and support in place, otherwise any rational spies would be able to spot it!
You'd also need to send something into a Trans Lunar Injection orbit (the launch and TLI burn are easily visible from the ground). the capsule can be tracked from Low Earth orbit for quite a distance by telescope.
You'd have to send
something to lunar orbit to transmit the telemetry and radio signals (which can be tracked from the Soviet union and elsewhere). You'd also need to carefully synchronise the speech cutoff with the telemetry cutoff and very carefully script the interactions between the astronauts and the ground to allow for the (simulated) speed of light delay.
The telemetry from the lunar lander and simulation of the conditions on the Moon would be murderously difficult to do. You'd definitely want to avoid TV transmissions from the Moon. You'd also need to curtail the programme after the first "landing" - fortunately public attention would drop off fast.
You'd definitely never send "lunar rovers" up - it's still pretty much impossible for us to simulate the driving of the rovers over lunar dust (watching the dust kicked up, you'd have to have a one-sixth gee vacuum environment large enough to encompass the rovers!)
Overall, given what you'd have to do to fake it, it would be
far easier to simply go through with it!
