The air ambulance service operating under the call sign Christoph Europa 2 is a cross-border helicopter emergency medical service (HEMS) based at the Luftrettungszentrum Rheine in North Rhine-Westphalia, Germany. Operated by ADAC Luftrettung, the service provides rapid emergency medical response and patient transport across a region that includes both western Germany and neighboring areas of the Netherlands. The station originated as a German Armed Forces rescue helicopter base operating the
Bell UH-1D and was transferred to civilian operation in 1998, when it adopted the "Europa" designation to reflect its international mission profile. Christoph Europa 2 employs an Airbus H135 (Christoph 24) configured as a flying intensive care unit, enabling medical crews to reach accident scenes quickly, provide advanced prehospital treatment, and transport critically ill or injured patients to specialized trauma and university medical centers. Its cross-border operating model has become a notable example of international cooperation in emergency medical services within Europe.
