There are only 3 helicopter pilots in Germany who can do these aerobatic maneuvers.
The German Bo 105 is a light twin engine multi purpose utility helicopter built by Messerschmitt-Bölkow-Blohm (MBB) which now belongs to the Eurocopter Group. Being the first light twin-engined helicopter in commercial service, it gained widespread use over rural areas (police and EMS / medevac) as well as offshore. The four-blade hingeless main rotor with composite blades ensures high maneuverability. All main systems (hydraulics, electric, fuel, lubrication) were designed to be fully redundant.
