When the crew of Apollo 11 returned to earth after their historic mission to the Moon, they were immediately placed in quarantine for 3 weeks. It was done to protect the Earth from the dangers of possible lunar alien life. Dr William Carpentier was the flight surgeon for the Apollo 11 mission and was placed in quarantine with the crew to monitor their health and check for any signs of alien life. He talks to Alex Last about his memories of working with the Apollo programme and life in quarantine.
