She was recording New York City's skyline from a commercial plane approaching LaGuardia Airport.

Reyes posted a video of the sighting and two screenshots of the mysterious flying cylinder that buzzed the commercial jet.

Here's the first screenshot of the object.

Reyes told NewsNation, "The first thing I did was email the FAA to let them know what I saw."

"Maybe it was a safety hazard, but unfortunately I haven't heard back from them, they didn't acknowledge my email," she said.

Thomas Wertman, the state director of the Mutual UFO Network in Ohio, told the New York Post the video shows the plane roughly at 2,500 feet. He said the object was "relatively close" to the plane.

He noted the object was on a major commercial flight path, which rules out it being a helicopter, military aircraft, or drone.

"Drones aren't supposed to fly at that altitude, at least legally," he said, adding, "If it were something related to [military] defense or law enforcement, you normally wouldn't see it so close to a major flight lane."
