This Jet Terrified the West: The MiG-25 Foxbat
I ran a search on my blog and I found numerous posts about various MiGs, but the only post that mentioned the MiG-25 was one about the number of Iraqi aircraft the Iranians shot down. So. While I still don't have all the various MiGs straight in my head, I'm getting a better idea.
This plane, or its successor sounds like it might have the basis for the Clint Eastwood movie Firefox.
P.S. Jet aircraft - The highest current world absolute general aviation altitude record propelled aircraft is 123,520 ft set by Aleksandr Vasilyevich Fedotov in a MiG-25M on August 31, 1977.
