Between about 8 and 10 o'clock on the night of March 13, 1997, hundreds of people near Phoenix reported spotting mysterious clusters of lights in the sky. A number of witnesses said that many of them seemed to come from a brightly lit, V-shaped craft, the size of at least several football fields.

"It was astonishing, and a little frightening," one local resident said. School administrator Susan Watson still remembers watching with her children as the massive object she describes as a "floating" city passed silently over their home. Air National Guard spokesmen later suggested the witnesses may have seen military flares that were dropped that night, while some proposed that observers were confused by aircraft flying in formation. But these explanations left many unsatisfied, particularly one witness who, for a decade, was reluctant to acknowledge he had also seen the vehicle: Fife Symington III, Arizona's governor at the time.

"I'm a pilot, familiar with most aircraft," Symington now says, "and what I saw is nothing like I've had any knowledge of."
