“Lufthansa crew and passengers overpowered a man who tampered with a cabin door on a Frankfurt-to-Belgrade flight on Sunday, the German carrier said, insisting the safety of the plane had not been threatened.
‘A passenger got up and tried to do something with the door, but was stopped by crew members and other passengers,’ said airline spokesman Andreas Bartels.”
