October 1990 - Saudi Arabia - large dark triangular object - 3 white lights - 20 seconds - no sound - no stars behind object

10/13/2005:  Tonight I viewed the televised Peter Jennings UFO report and it reminded me of this incident.  
While serving in the US Air Force, Operation Desert Shield during October 1990, I observed a dark triangular shaped object moving across the sky at approximately 22:30 hrs.  
It made no sound.  It had 3 white lights, 1 at each corner of the triangle. 
My location was a remote desert airstrip having little interference from ground lighting.  There were many stars visible, but none were visible within the triangle itself.  The moon was approximately full.  
The object moved across my field of vision in approximately 15 -20 seconds.  It was much larger in size than the moon; like comparing the size of a quarter dollar to the size of my hand held at arms length.  
Its altitude was unknown.  
I remember bringing this incident to the attention of several others at the time it occurred.  \\
During my 22 years of AF service, I witnessed many types of aircraft in flight.  I have no idea what that object was!
Witness indicates that the date of the sighting is approximate.  PD
