I believe 100% that the landings were real. I can't believe that if they were fake that every scientist in the world would play along with the lie.

I think the usual HB idea is that scientists are easily fooled. In the HBs' view, scientists and engineers really aren't any smarter than average folk, but they certainly are cleverer, having awarded themselves diplomae to prove their superiority. This view of scientists and engineers is being played out in apollohoax.com right now. Reminds me of the Scarecrow in The Wizard of Oz, who only needs a diploma ("Dr. of Thinkology" IIRC) to come up to speed with everyone else.
