I have heard of most of those pilots, I have read several books from their perspective, the better part of me knows that those numbers aren't accurate. Many don't match US records and the kill criteria was different. In "MiGs Over North Vietnam" by Roger Boniface, the state-sanctioned story is told and while it is fascinating, it's embellishments remind me of the way the DPRK teaches about the Korean War.
Inflations, embellishments, lies, pride, nationalism, etc.
Here's an example:
On the night of 27 December 1973(sic) Pham Tuan flew Red-5121 to within 1,100 yards of a B-52 (unclear which model) and shot it down with Atolls. The US has never acknowledged a loss to fighters of a B-52.
On the other hand, in "Stratofortress: The Story of the B-52" the author interviews 2 B-52G (less ECM) gunners who each claimed a MiG-21 shot down around the same time frame. The VPAF doesn't acknowledge those losses either.
MiGs Over North Vietnam was hard to read because listening to the accounts of VPAF pilots was like listening to Bagdad Bob claim that US soldiers are committing suicide by the hundreds outside the gates of Bagdad.
