LaGuardia Airport's Runway 4/22 reopened Thursday around 10 a.m. following the fatal collision between a Air Canada jet and firetruck Sunday night, the Port Authority of New York and New Jersey confirms.

The opening comes four days after the crash that killed two pilots and injured roughly 40 passengers, most of which have been released from the hospital at this time.

It took two large trucks to remove the mangled Air Canada plane and firetruck.

"Since the removal of the plane and truck late Wednesday, the runway and associated infrastructure has been repaired, inspected, and confirmed to meet FAA regulations for safe operation," the Port Authority said in a statement, "The reopening of Runway 4/22 will help restore full operational capacity at LaGuardia, though travelers are still encouraged to check with their airline for flight status."

The National Transportation and Safety Board is continuing its investigation.
