A Lufthansa plane bound for Frankfurt slipped from the runway at Belgrade's airport while attempting to take off early on Thursday, dpa quoted local media as reporting. None of the passengers and crew aboard were injured, while the damage to the aircraft was minimal, Radio B92 reported. Air traffic was interrupted while the craft, which skidded about 70 metres off the runway, was removed. The probable cause of the accident was black ice, though a plane belonging to the Serbian JAT Airways company landed with no problems immediately before.
