The MiG-23
This Soviet fighter aircraft, The Mikoyan-Gurevich-23, was the first-ever aircraft to have a “look-down/shoot-down” radar. The older model was preferred more because the new one had a smaller cockpit and limited view. After the Cold War, the plane was retired but the original is still used.
The Yak-42
Sir Halffast commented on the design of the Yak-42 by saying that it was so terrible, he could not believe it was being used by 2013. He said, “I had the misfortune of flying in one on a domestic Ukrainian flight from Kyiv to Donetsk and was amazed. For one, the top of the entry door is chest high on a 6’0″ man. And of course, it has the horrible Soviet seats that fold flat forward with little provocation. And the rear stairway that rattles in flight as if it’s about to pop open at any moment.”
