Little trivia, but the Mig25 and SR-71 met over Israel in 1967, both you big guys spying on us as we (allegedly) went nuclear — and during a spat with our ever-so-friendly neighbors.
The SR-71 had a serious malfunction and the pilot wanted to land at Tel-Aviv (and we were fine once we figured out who it was and promised not to touch the plane or the pilot), but tensions were high and the CIA wanted us to all die, so they ordered him to continue on.
Luckily, he made it to Europe somewhere. I assume Turkey.
Your account is plausible and Turkey was probably where he landed.
I would guess that he probably took off from somewhere in Turkey.
