The Yak-42
The Yak-42 is a common joke among pilots who had the displeasure of flying this thing. The cockpit was tiny, the chairs were broken, and the back stairway never seemed to stop rattling during the flight which made everything feel scary. It was in operation until 2013.
The Ilyushin II-62
An anonymous pilot submitted his feelings about the plane and it reads as follows: "It still uses flight manual controls, no power assist to move those flight control surfaces. If some ice gets in a hinge, it's just your muscles that will break it loose. It also has a history of failed thrust reversers and exploding engines that damage neighboring engines." There you have it! It's a death trap!
