NEW YORK — A JetBlue passenger jet lost its balance and tipped like a seesaw while unloading Sunday at New York’s John F. Kennedy International Airport, according to the airline.

“Once at the gate, due to a shift in weight and balance during deplaning, the tail of the aircraft tipped backward causing the nose of the aircraft to lift up and eventually return back down,” JetBlue told CNN.

Nobody was injured in the incident, JetBlue Airways said.

The aircraft’s nose in the air and front landing gear are seen hanging while the plane is parked at a jet bridge, in video posted online. At least one opened cargo door in the front half of the plane can be seen.

JetBlue is “reviewing this incident” and the plane will be inspected before flying again, the airline said.

The Port Authority of New York and New Jersey, which oversees the airport, said the incident did not disrupt any other operations at JFK. — CNN
