I found this UFO in an old Shuttle Atlantis video on a NASA website today. The UFO is white and triangle shaped, following the dropped rocket that helped the shuttle take off. 

If you remember the Shuttle Atlantis, you will also remember how CNN aired news declaring a UFO was preventing the Shuttle Atlantis from landing on time, and it was delayed in orbit being followed by several small objects. Here is one of those objects close up.
