The Antonov An-2 is an extremely durable, light, single-engine biplane which first flew on 31 August 1947 and was the first plane designed by Antonov. It is used as a light transport, capable of carrying 12 passengers, and for parachute drops and agricultural work. Its slow-flight and STOL capabilities make it suited for short, unimproved fields, and some specialized variants have also been built for cold weather and other extreme environments. The Guinness Book of World Records states that the 45-year production run for the An-2 was the longest ever, for any aircraft, only recently beaten by the Lockheed C-130 Hercules. (NATO reporting name Colt). 11915 aircraft were produced in Poland.
