Münchberg (dpa / lby) - A rescue helicopter called to an accident blocked a motorway access in Upper Franconia for around two hours due to a technical defect. The three injured were ultimately taken to hospitals in an ambulance, a police spokesman said on Monday. They were less seriously injured in the accident near Münchberg (Hof district) than initially assumed. The helicopter, which had a problem with the rotor, was finally repaired and took off again on Sunday evening.
