Launch Complex 39 (LC-39) is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, United States. The site and its collection of facilities were originally built for the Apollo program, and later modified for the Space Shuttle program. A Saturn V rocket launched Apollo 11 from Launch Complex 39 site at the Kennedy Space Center on July 16, 1969, at 13:32:00 UTC (09:32:00 EDT local time) with Neil Armstrong aboard. Armstrong's wife Janet and two sons watched from a yacht moored on the Banana River. During the launch, Armstrong's heart reached a top rate of 110 beats per minute.He found the first stage to be the loudest—much noisier than the Gemini 8 Titan II launch. The Apollo CM was relatively roomy compared to the Gemini spacecraft. None of the Apollo 11 crew suffered from space sickness, as some members of previous crews had. Armstrong was especially happy, as he had been prone to motion sickness as a child and could experience nausea after doing long periods of aerobatics.
