A perplexing celestial phenomenon was observed in the Arizona sky on May 6, according to a recent testimony published on the National UFO Reporting Center (NUFORC) website.

Around 9:20 pm local time, a Tucson resident was enjoying an evening on his back patio when a bright white flash caught his eye. "At first, it looked like a meteor falling from east to west at an angle of about 45 degrees," the witness, who remained anonymous, recounts.

However, just as the object seemed about to burn out, the celestial phenomenon made a startling change in trajectory. "It suddenly made a 90-degree turn, shooting straight upwards vertically, then immediately changed course southward before disappearing," the observer describes.

Perplexed, he quickly ruled out the hypothesis of a fighter jet, having heard no engine noise despite the apparent proximity of the phenomenon, estimated to be about 100 kilometers away. "It happened way too fast to be a jet," the witness insists.

The descriptions of the object, its bright white luminosity leaving a trail in its wake, and its inexplicable changes in direction defy simple explanation. Was it a strange rocky bolide burning up in the atmosphere? Or a constructed object of indeterminate shape and nature?

"I thought it was a meteor until it changed direction," the baffled observer admits, days after the event. For now, this witness joins the long list of people reporting having witnessed an unidentified flying object in the American sky.
