New York's LaGuardia airport has been closed until further notice due to a collision between an Air Canada Express plane and a ground vehicle. The Federal Aviation Administration (FAA) issued a ground stop for the airport late on Sunday, indicating a 'high' likelihood the order would be extended. Reports state that the plane, which was arriving from Montreal, collided with a Port Authority vehicle while it was slowing down to approximately 24 mph upon landing. The aircraft, a CRJ 900 model carrying around 70 to 90 passengers, sustained considerable damage, but there have been no reports of injuries. The incident has prompted a thorough examination as LaGuardia airport remains shut down.
