This video shows UFO's on NASA's own videos of space missions. It also shows how if UFO's were capable of traveling at or faster than the speed of light, they would not be visible to the naked eye. The narrator also is able to calculate the speed of the UFO's at the time of 900,000 miles per hour & some sizes of UFO's from 2 to 3 miles in width.
It's a long video (an hour and a half long) so if you're going to watch this, set aside some time to specifically watch this.

Before people go saying "Oh UFO's aren't real! Blah blah blah", watch the video first.
