The Inquirer is reporting that an investigation is taking place by the National Transportation Safety Board following an accident on a flight to Dublin Airport.
The Aer Lingus flight was heading from Philadelphia International Airport on Friday evening when a worker at the airport was badly injured following a freak accident with the plane.
As the flight was about to depart, the 60-year-old man was caught "under an airplane moving tug and wheel of the plane."
The man is still in critical condition and the investigation as to what went wrong is still in the early stages.
The man in question was not working for Aer Lingus but a different Dubai-based airline on the ground at the time of the 'pushback'.
Pushback is an airport procedure where the aircraft is pushed away from an airport gate by a special low-profile vehicle called pushback tractors or tugs.
