Astronauts Encounter UFOs over Earth; recorded by NASA

I find this simply fascinating, Youtube user LunaCognita has posted several video compilations of NASA archival footage that appears to show instances of astronauts witnessing and discussing UFOs near the orbiter vehicle.
Some of the clips are of poor resolution (evidenced by the fact that most filmed objects are indistinguishable from debris), and some of the enhancement techniques are questionable. However, the audio clips are the most compelling part of the videos... Take a few minutes to watch these clips.
