Antonov An-2 landing at Hahnweide.
The An-2 was designed as a utility aircraft for use in forestry and agriculture. However, the basic airframe is highly adaptable and numerous variants have been developed. These include hopper-equipped versions for crop-dusting, scientific versions for atmospheric sampling, water-bombers for fighting forest-fires, flying ambulances, float-equipped seaplane versions, lightly armed combat versions for dropping paratroops, and of course the most common An-2T version, which is the 12-seater passenger aircraft.
