'Mysterious floating objects' in NYC were birthday balloons, not UFOs

New York, Oct 15 (ANI): Students of a Westchester elementary school rubbished claims of UFO sightings, saying that they were just a bunch of balloons.

The students believe that the puzzling orbs floating over Chelsea were likely a bundle of balloons that escaped from an engagement party they held for their teacher.

"UFO? They're crazy - those are our balloons. To me it was the most automatic thing. But it's all over YouTube," the New York Daily News quoted Angela Freeman, head of the Milestone School in Mount Vernon, as saying.

A parent was bringing about 40 iridescent pearl balloons to the school for language arts teacher Andrea Craparo when the wind spent a bunch away.

"They looked big and they were all together, so it looked like one UFO," said fourth-grader Nia Foster, 9.

Awestruck onlookers began calling the NYPD and the FAA when mysterious flying objects appeared over Manhattan.

Also, helium-filled balloons tend to change shape at high altitudes as the gas expands - making them look abnormal from below, experts said. (ANI)
