An airplane passenger took flying saucer speculation to new heights when she spotted a possible UFO soaring above the Big Apple — baffling experts and sending federal aviation officials on a fact-finding mission Thursday.

Michelle Reyes was on a commercial airline flight above LaGuardia Airport on March 25 when she captured video footage of a mysterious “flying cylinder” out of her plane window, she said on Facebook.

“The first thing I did was email the FAA to let them know what I saw,” she told NewsNation Wednesday.

“Maybe it was a safety hazard, but unfortunately I haven’t heard back from them, they didn’t acknowledge my email.”

She said another person on the flight saw the out-of-this-world object and was stunned.

“It’s a little nerve-wracking that someone else saw what I saw,” she said.
