NEW YORK — Authorities say a Delta plane from Atlanta has skidded off a runway while landing at LaGuardia Airport and has crashed through a fence. Port Authority of New York and New Jersey spokesman Joe Pentangelo says the MD-80 went off the runway at around 11:10 a.m. Thursday. The Fire Department of New York says no injuries have been reported. Images show the plane resting in the snow with the nose of the jet through a chain-link fence. Atlanta-based Delta Air Lines says passengers are deplaning via aircraft slides and have been taken to the terminal on buses.
