Did you think, as I did, that the TFX/F-111 was Secretary of Defense Robert McNamara's only joint-service aircraft project? No, there were two others: the F-4 Phantom II and the A-7 Corsair II, US Navy fighters more or less forced upon, but eventually enthusiastically adopted by, the US Air Force.
I volunteer as a walking tour docent at Tucson's Pima Air & Space Museum, where I tell visitors about the USAF F-4E we have on display inside the main hangar. Visitors who take our outdoor tram tour get to see two earlier Vietnam-era models, a Navy F-4J and an Air Force F-4C. I came into the USAF when the F-4 was king, and though I never had to opportunity to fly it I've always been interested in the Phantom II, especially the differences between early and late models of the aircraft.
