Apollo 11

The Apollo 11 Moon landing, the first "official" landing by Humans on the Moon, happened on July 20, 1969.

The mission
Coordinated by Mission Control at the Kennedy Space Center in Florida, the Apollo 11 lifted off on July 16. En Route to the Moon, the crew encountered unnamed aliens. Mission Control, as well as Torchwood, would know of this, but not the public. After getting locked by an overzealous secret services officer, Spencer, the Doctor ended up locked up in the Center, though gained release in enough time to greet the aliens due to land on the Moon in a flying saucer prior to the Apollo. The Doctor then witnessed the landing. (WEB: Blue Moon)

(WEB: Blue Moon) With interest in the landing so intense, public places virtually emptied as people all over the world glued themselves to their televisions.
