A Lufthansa CityLine technician at Manchester has apparently been seriously injured while servicing a Bombardier CRJ aircraft that was bound for Hamburg on a ferry flight.
There is evidence that the individual was injured by an explosion, and unverified reports point to a possible tyre burst.
A spokesman for the German regional carrier says: "There was an incident at Manchester Airport this morning involving a technician at Lufthansa CityLine. We have no further information about what happened at the moment.
"We can confirm, however, that a large bang was heard around the aircraft and the terminal building."
He adds that the technician is undergoing treatment at a local emergency unit for his injuries.
