The MiG-23
The Mikoyan-Gurevich-23 was a Soviet fighter aircraft. It was the first plane they had that came with a “look-down/shoot-down” radar. Like the other planes on the list, its earlier model was more popular. After all, the pilot needed to sit in a cramped cockpit and had limited vision in the MiG-23. After the Cold War, air forces kept their MiG-21s but let go of their MiG-23s. A number of the latter is still in use today.

The Yak-42
Sir Halffast talked about his experience with the Yak-42 in one Jalopnik article. He said that its design was so bad that it was terrible that it was still in use in 2013: “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.”
