In July 1976, 32 West Berliners are seriously injured in a bus accident in Afghanistan. To avoid political problems on the flight to Berlin, Siegfried Steiger charters an Interflug wide-bodied aircraft from the GDR Minister of Transport. The aircraft takes off from Stuttgart with 30 doctors and paramedics on board and flies the injured from Kabul to East Berlin. There they are taken by 32 West Berlin ambulances through the sector border to West Berlin clinics.
