military sighting of saucer like object in Missouri

I was in the air force, stationed at Whiteman AFB, working in the command post.  At approx. 2100 hours, I received a call from the Wing Security controller asking me to tune my radio to the base frequency.  I did and started listening to a series of events that began with a missile site losing power and a strike team being dispatched to the site only to see this saucer shaped device hovering over the site.  When the team was ordered to advance onto the site, the device backed away and power returned as soon as it was away from the site.  This happened in the southernmost flight area OF THE MISSILE COMPLEX.  tHE DEVICE BEGAN A SLOW NORTHERLY ROUTE, TRACKING OVER MISSILE SITES AS IT WENT.  eACH TIME IT WOULD CROSS A SITE, THE POWER WOULD BE LOST AND RETURN SAS SOON AS IT PASSED AWAY.  tHE DEVICE CAME NEARLY OVER THE BASE AND WAS VISUALLY SIGHTED BY THE WEATHER OBSERVERS AND CONTROL TOWER PERSONNEL.  iT CONTINUED NORTH OUT OF THE WING AREA WITHOUT INCIDENT EXCEPT FOR THE POWER OUTAGES. I turned all information into the AF Project Blue Book and never heard of the situation again.
We have attempted to telephone this witness, in order to obtain more details, but have been unsuccessful in reaching him, to date.  PD
