The Chelsea UFO theories have been deflated.
The mysterious objects that hovered over West 23rd Street on Wednesday were almost certainly errant party balloons.
And they came not from Mars, but Mount Vernon.
“It was just a freak thing. Frankly, I’m shocked by it,” said Angela Freeman, head of the Milestone School in the Westchester suburb, where the cluster of balloons was inadvertently launched.
“The kids had an engagement party for a teacher, and a mother brought four dozen balloons, and she’s coming through the door. It is very windy in Mount Vernon. Suddenly, 12 of the balloons let loose.”
