Early 60's Triangle Craft

While laying on our backs on the sidewalk and talking, I suddenly noticed what I first too to bwe a searchligh sweeping across the sky. Even in the clear desert air a searchlight such as those used at grand openings can be discerned. As I focused on the light it resolved into a V-shape. I could see six points of light and I thought it was six seperate ships but now I believe it might well have been one triangular craft with six light showing. It traveled from a little right of straight up to off the horizon in about 5 seconds. This occured over Davis-Monthan AFB and the craft(s) travelled south toward Mexico. Having been raised in the Air Force and knowing a lot about aircraft, I am sure that it was travelling at least ten times as fast as anything we had in the air at that time.
Date may be approximate, although the witness does not indicate that fact.  PD
