Thanks for the speedy replies:
1: I agree that the text details by Pensacola rule out F-8 145347 - the time scale eliminates this possibility.
2: If Crusader 150311 was hit by a Surface-to-Air missile over North Vietnam, it is unlikely to be the aircraft at Miramar.
However, as the pilot was captured and is shown as a POW, I wonder if it the case that the Miramar Crusader was repainted to represent 150311.
However, the Bu # on the Miramar aircraft is in the 142*** sequence, so again I have doubts.
Thanks both for the interest shown - will await further response on both Miramar aircraft.
Best regards.
Peter
