An empty Airbus SE A340-300 long-haul aircraft owned by Deutsche Lufthansa AG was damaged after a tow truck maneuvering the plane around Frankfurt airport caught fire.
About 10 people were taken to the hospital after for smoke inhalation, a spokeswoman for the carrier's Lufthansa Technik maintenance unit said.
The division operates plane-towing vehicles under the Leos brand in Frankfurt.
The twin-aisle airliner was being moved with no passengers on board in preparation to operate as Flight LH426 to Philadelphia, and must now be inspected for damage, a spokesman for Lufthansa said.
A reserve plane will be used for the route instead, and the flight will leave on time as it's an afternoon service, he said.
