Buzz Aldrin once punched a man for calling Moon landing hoax

The second man to walk on the Moon, Buzz Aldrin once punched a conspiracy theorist for claiming the first-ever Moon landing was fake. The man had asked the former NASA astronaut to "swear on the Bible" about walking on the Moon. Aldrin, who turns 88 today, was part of the Apollo 11 crew, which included Neil Armstrong and Michael Collins.
