The helicopter landed on a grassy field, the crew carries the medical and technical equipment on a stretcher to the accident site. These missions with rescue helicopters were pilot projects of the Luftrettung (air rescue service) of Bundeswehr, Bergwacht (mountain rescue service) and doctors of Munich hospitals. As of 01.11.1970 the Bundeswehr withdrew from the project, the ADAC stepped in and with "Christoph 1" established the first continuous operation of a (civilian) rescue helicopter.
