1969 - Apollo 11, the first U.S. lunar landing mission, is launched from Cape Canaveral, Florida, on a historic journey to the surface of the moon. After traveling 240,000 miles in 76 hours, Apollo 11 entered into a lunar orbit on July 19.
The greatest achievement of my lifetime. Perhaps the only thing that comes close is winning the Cold War, and ending (okay, massively reducing) the threat of global annihilation.
