The Flettner FL 282 Kolibri ("Hummingbird") is a single-seat intermeshing rotor helicopter, or synchropter, produced by Anton Flettner of Germany. According to Yves Le Bec, the Flettner Fl 282 was the world's first series production helicopter.
Intended roles of FL 282 included ferrying items between ships and reconnaissance. However, as the war progressed, the Luftwaffe began considering converting the FL 282 for battlefield use. Until this time the craft had been flown by a single pilot, but by then a position for an observer was added at the very rear of the craft, resulting in the B-2 version. Good handling in bad weather led the German Air Ministry to issue a contract in 1944 to BMW to produce 1,000 units. However, the company's Munich plant was destroyed by Allied bombing raids after producing just 24 machines. Towards the end of World War II most of the surviving FL 282s were stationed at Rangsdorf, in their role as artillery spotters, but gradually fell victim to Soviet fighters and anti-aircraft fire.
