The Moon Landing Hoax conspiricy theory BUSTED with Dave's original proof.
Dave does something no one else has done before - compare the original Apollo 17 16mm ascent camera footage to the Lunar Reconnaissance Orbiter (LRO) photos. Will footage from 40 years apart match up to confirm the moon landing?
