This documentary was released in 2000 and has received very little notoriety.

The Secret NASA Transmissions, delves into the investigation of highly secretive NASA communications between Earth and Astronauts of strange things they witnessed while out floating in the cold vacuum of space. This documentary is a compilation of UFO sightings by NASA Astronauts and delves into the facts around a secret independent study to monitor the digital video cameras on all NASA Space Shuttle missions.

Martyn Stubbs recorded over 2,500 hours of live NASA video transmissions over a period of five years. Some of this footage shows what appears to be intelligently controlled UFOs caught on NASA's own video cameras.

In all, the documentary has some fluff but some good material as well. Worth taking a look.
