Its odd to believe they have been scrapped, because one or two can be put to the "scrapping" job. Those migs appeared to be used to test its aerial capabilities.
Although americans using fulcrums in red flag seems weird too because you'd want your pilots to train in your equiptment, and that way you learn how to compete with the foreign pilot.
On this war the US forces have dug out some MiG-25s out of the sand, I wonder if the US will use them for testing as well?
Hmm...well we got the info, now where are the pictures of the MiG-29s?! lol
here's some pictures of the MiG-25 being dug out if you're interested.
