I also had the opportunity today to fly as a passenger in the AN-2 that I showed in the picture yesterday. Jerzy used to crop-dust in an AN-2 and he says it is a 1000 hp radial engine. The picture below is looking out the window at the second AN-2.
The pilot was quite busy in the cockpit, and it took both of them to fly the plane. The control forces looked pretty heavy, the second pilot had to operate the throttle, while the first pilot concentrated on controlling the plane!
