Passengers taking off and landing at New York’s LaGuardia airport have a front row seat into the twisted wreckage of Air Canada Express Flight 8646, which still lies by the airport's Runway 4. The mangled wreck, which was carrying 72 passengers and four crew members from Montreal when it collided with a fire truck late Sunday, will remain where it came to a stop until investigators from the National Transportation Safety Board (NTSB) have completed their work.
