That MNvap "study" would be like taking my original F-4 Phantom that was introduced in about 1965 and studying its abilities for 10 years. But in the ensuing years there were numerous feenominoominalistic updated versions of F-4 that made the original F-4 Phantom almost archaic. Compared to the later F-4 (KDS) version that I flew in 1975. PS I hope!
