The Antonov An-2, NATO reporting name 'Colt', is renowned as the largest single-engined biplane in the world. More than 18,000 examples have been built, and even though the first prototype took to the air way back in August 1947 this rugged utility biplane, capable of fulfilling a wide range of roles, remains very useful to operators in many countries. Capable of extremely slow flight, and even of flying backwards in a suitable headwind, the An-2 has no quoted stalling speed, and will instead sink gently towards the ground at a rate of descent similar to a parachute! The Estonian Air Force has two, both used for various transport tasks with the Fixed-Wing Squadron at Ämari.
