"On November 19, 1969 - Apollo program Apollo 12 astronauts Pete Conrad and Alan Bean land at Oceanus Procellarum (the "Ocean of Storms") and become the third and forth humans to walk on the Moon." - World of Engineering
Amazing how famous Neil Armstrong and Buzz Aldrin became in history yet how obscure the third and forth people to walk on the Moon became to the common person. Like how nobody remembers the second person to break the 4-minute mile. Or the second person to break the sound barrier.
