what i saw avoided radar and physics flying so slow

at the time i was in the usaf a firefighter stationed at a sac base loring.i was on dispatch that night and finished my shift at 1145 pm 
upon arriving at my quarters on base i exited my car on this foggy night hearing a sound like a propeller aircraft as the sound grew closer i looked up and flying over my head is what looks to be the markings of the underside of a k-c 135 tanker air craft flying at a speed too slow for such an aircraft 
i watched this craft till it flew far away from me and then it seemed to land in the woods surrounded by a perfectly round glow of multicolored light i rember seeing this light as a child in new york  same glow. once it appeared to land i cant remember if the glow went away or not. 
here is the stumper, as a usaf firefighter on a b52 and kc135 base you have a top clearence as a fire control dispatcher you have direct contact with all base priority agencies  being in constant touch with the control tower.  note: dod regulations forbid  dod aircraft from flying over living quarters airspace on installations----fact-when i rushed into the house alerted my wife and then called my friends at the control tower to ask about this they told me that they saw NOTHING on the radar that night and that no sorties were scheduled from early evening till the next day and reiterated the no fly zone rule.
what flew over my head so slow disguised as a dod aircraft that night my report to the tower was official i demanded that it was also recorded
Witness indicates that the date of the incident is approximate.  PD
