UFO - Phoenix Lights, March 13, 1997.

The number of lights in the boomerang seemed to vary along the path of the object from 5 to 7 according to the witnesses. Some of the witnesses described this formation or object as huge, even up to 1 mile in span. It traveled, according to all witnesses, on a trajectory from Northwest to Southeast. It traveled at slow velocity along most of its course with one exception where it seemed to accelerate quickly. Its altitude was estimated to be below 5,000 feet. We know this is simply an estimate as it is difficult to determine the altitude of a flying object in the night sky. The witnesses agreed they could hear no sound emanating from the boomerang. In March 2007, former Arizona Governor Fife Symington III said that he had witnessed one of the “crafts of unknown origin“ during the 1997 event, but noted that he didn't go public with the after the lights, Symington held a press conference, stating that “they found who was responsible“. However, he quickly changed his mind. In an interview with The Daily Courier in Prescott, Symington said: 'I'm a pilot and I know just about every machine that flies. It was bigger than anything that I've ever seen. It remains a great mystery. Other people saw it, responsible people. I don't know why people would ridicule it.' —Fife Symington III,
