Italian Interior Ministry specialists believe that "human error" was the cause of a tragedy at Milan's Linate airport on Monday morning. According to the ministry's information all the 114 people on board an SAS airliner and the four-man crew of a private German Cessna plane were killed in a collision on the runway. The authorities are trying to establish how many airport staff also lost their lives after the Scandanavian liner hit the luggage section where they were working. Sixty bodies have so far been recovered form the wreckage. Two airport staff members have been found alive and taken to hospital.
