I saw a UFO just last night. It was a steady bright light in the west, slowly moving in my direction....Then it got close enough so that I could tell it was the main landing light of a C-5 on approach to Travis AFB.....It was "unidentified" until I could tell what it was.
I saw it too. I used to work in the tower at Travis. The C-5s and KC-10s are going over all the time.
