I flew a Cessna 152 "backwards" during my checkride. Any airplane can fly backwards relative to the ground given sufficient wind. What is impressive about the An-2 is its super-slow stall speed (the minimum airspeed necessary for flight). From Wikipedia: "The An-2 indeed has no stall speed quoted in the operating handbook. Pilots of the An-2 say one can fly the aircraft in full control at 30 mph (as a contrast, a modern Cessna four-seater light aircraft has a stall speed of around 50 mph)."
