We saw the objects so many times we got use to them.

I was stationed as a security officer at Wurthsmight AFB, which is a SAC installation.  Let me explain this was not one sighting, but many, all at night, except one, which I will use another form to explain. 
I was guarding a Alert Ready B-52 with two H bombs in its bay.  We ofted looked up into the night sky because it was very dark and we were able to view many stars.  The object we often seen.
Was a round object about 2 thousand feet over the aircraft, it was very bright and appeared to hover for approx 5 minutes they it took off what seemed like the speed of light, one minute it was there and the next it was gone.  
We never reported these because we felt tha they would think we were making them up. However, they were aware of the objects because one time they sent two F-104 jet fighters after them.  Guess it didn't help because they kept coming back.
Source of report indicates that the date of the sighting is approximate.  PD
