More and more evidence is surfacing that NASA has known about UFOs since the early 1960s and have been covering it up. Here is a video of the Apollo 11 mission broadcast where the astronauts walking on the Moon saw serveral UFOs and were amazed by what they saw.

Here are some quotes from the NASA Mission Broadcasts from the astronauts.

"At no time, when the astronauts were in space were they alone: there was a constant surveillance by UFOs."
--NASA's Scott Carpenter

"I believe that these extraterrestrial vehicles and their crews are visiting this planet from other planets which obviously are a little more technically advanced than we are here on Earth." --Colonel L. Gordon Cooper (Mercury 9, Gemini-5 Astronaut)

"Mission control, We have a UFO pacing our position, request instructions!"
-- Astronaut Cady Coleman NASAtransmission shuttle mission STS-73
"In my official status, I cannot comment on ET contact. However, personally, I can assure you, we are not alone!
--Charles J. Camarda (Ph.D.) NASA Astronaut

"All Apollo and Gemini flights were followed, both at a distance and sometimes also quite closely, by space vehicles of extraterrestrial origin - flying saucers, or UFOs, if you want to call them by that name. Every time it occurred, the astronauts informed Mission Control, who then ordered absolute silence."
--Maurice Chatelain, former chief of NASA Communications Systems.
