Emergency slides were deployed around 9 p.m.as passengers evacuated the plane originally bound for San Francisco, according to the Federal Aviation Administration.
According to ABIA, at 8:22 p.m., a United Airlines plane was taxing out of gate 19 while an American Airline's plane was stationary at Gate 21 when, somehow, both plane's wings collided. "Go down the slides and run away from the plane!'" one passenger told Gothamist.
Passengers were kept on the planes as the pilots waited for permission from the FAA to deboard the airliners.
At LaGuardia, Concourse C in Terminal B was closed for approximately 45 minutes as police searched for a man seen on surveillance video walking right past security. He gave the evacuation order and we heard screaming coming from the back of the plane.
The agency did say the two Boeing 737 planes came into contact in the ramp area, with preliminary information showing the wingtip of United Flight 898 came into contact with the tail section of the American flight.More news: Arrests in Manchester, Tripoli as police hunt bomber's network
