I am of the opinion that this FOX News report about official NASA TV UFO footage, is the strongest evidence for UFOs flying near the NASA Space Shuttles!
Mr. Wayne Hale, NASA Space Shuttle Program Manager, admits here that NASA rarely finds out where these objects come from!!!
Didn't Mr. Hale, here, in effect admit that UFOs fly close to the NASA Space Shuttle on virtually every Space Shuttle Mission (meaning: NASA does neither know what these unidentified objects are nor where they come from)?! NASA officials have repeatedly said in several NASA documentaries I have seen, that NASA has REGISTERED and TRACKS EVERY PIECE of space debris which floats near the Earth.
Maybe some of you are thinking the same thing I am thinking?
54 seconds into this video, you will see that one of the UFOs starts to accelerate, while the three other UFOs seemingly do not move:
