Two people sustained minor injuries after a Copa Airlines passenger plane collided with a UPS cargo aircraft while taxiing at Miami International Airport in the United States on Saturday night.

The collision occurred at about 9:15 p.m., when the wingtip of a Copa Airlines Boeing 737 struck the nose of a UPS Boeing 767, according to the Federal Aviation Administration (FAA).

Miami International Airport’s Communications Director, Greg Chin, said the injured individuals were treated at the scene by fire and rescue teams.

The Copa Airlines flight had arrived from Panama City, Panama, while the UPS aircraft was preparing to depart for Bogotá, Colombia, when the incident occurred.

The FAA said air traffic controllers had instructed the UPS crew to give way to the Copa flight. The agency has launched an investigation into the collision.

Air traffic control audio captured the Copa pilot reporting that another aircraft had struck the plane. The UPS pilot subsequently acknowledged that his aircraft had clipped the Copa jet’s wing.

Copa Airlines later confirmed that all 166 passengers and six crew members had safely disembarked and that the aircraft had been returned to the terminal.

A photograph of the UPS aircraft showed significant damage to its nose, including a large opening in its outer panels.

UPS said its crew was safe and pledged to cooperate with authorities investigating the incident.

The collision came a day after a nationwide flight grounding disrupted air travel across the United States, leaving passengers stranded and forcing widespread cancellations and delays.
