As far as I know, that definitely didn't happen.
I'll try to find out more ,but my comkmon sense says no...
No, probably not, but you never know. I don't know if any of those pilots actually flew combat aircraft, or only the transport missions. Any type, not just Mirage III. Let us know if you find out.
We've seen pretty old fighter pilots, mostly instructors and test pilots that get to an exceptional high age and still fly. I can imagine such a person getting into the actual fight in a war, regardless of whether he's still in active service, reserve, being called upon, or just volunteering.
But I suppose most if not all were just a bit too old, and the FAA had enough younger but still experienced pilots.
Wouldnt the only WWII fighters been like high end commanders by that time if they stayed in the military?
Surely, most remaining with the air force at that time, would probably be at senior non-flying positions. But that's doesn't mean they don't keep up their flying skills and won't fly in case of war. At least one did fly combat missions dropping troops/supplies, it's in the Reuters article linked above.
