That’s what happens when you wing it!

An Airbus A330 hit a hangar at JFK yesterday while parking without any ground crew to guide the way, law-enforcement sources said.

The red winglet of the Brazilian TAM plane broke off when it became lodged on the side of Hangar 3 in the 11 a.m. incident. A worker in the plane suffered a panic attack and was removed by rescuers from the Port Authority Police Department and EMS and treated at Jamaica Hospital.

Last night’s flight, meanwhile, was canceled for repairs.
