20 July 1969. Charles Duke (left) has just given the order to land, the ‘go for landing’. Eleven minutes later, at 14:17 (Houston local time), the Lunar Module ‘Eagle’ with Neil Armstrong and Buzz Aldrin landed on the Moon. Duke’s reaction to the landing of Apollo 11 reported by Neil Armstrong (“The Eagle has landed.”) is frequently repeated: “Roger, Tranquillity. We copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot.” To the left of Duke are the astronauts Jim Lovell, commander of the Apollo 13 mission that flew in April 1970, and Fred Haise, Apollo 13 Lunar Module pilot.
