EF-111A Raven
Friend of mine in UPT got an F-111 but never flew them due to problems early on.
Another fellow aviator later went into FBs and was lost over the North Atlantic. They never found so much as an oil slick.
Instructor friend flew them and wadded one up at Holloman after an engine failure.

The Aussies still fly the FBs.
Oh.. last paper I wrote in USAF ROTC was on the TFX which later became the -111. Long and difficult teething and it got too fat, too heavy and too fast for the Navy. It was McNamara's baby... one plane to do everything.
