New York's LaGuardia airport has been closed until further notice after an Air Canada Express plane and ground vehicle collided. The Federal Aviation Administration issued a ground stop for the airport late on Sunday night and indicated there was a high likelihood the order would be extended. CBS News, the BBC US partner, reported that the plane was arriving from Montreal and had just landed, slowing down to about 24 mph when it collided with a vehicle belonging to the Port Authority of New York and New Jersey, which operates the airport. The smaller model CRJ 900, carrying about 70-90 passengers, sustained significant damage, but at this time, no injuries have been reported.
