Ah, the last time we had a technological goat rope was under McNamara (the “genius” behind the Edsel and the World Bank).
His product?
The F-111...a do all for the USAF and Navy.
The Navy rightly rejected it and the USAF put up with it as a bomber (sort of) for many years.
It wasn’t really a bad plane...but it was trying to be an “everything”...with predictable results.
Saw F-111's exercising with British Buccaneers along the Tyne valley in 1989. I remember standing on the parapet of one of Hadrian's fortresses on his wall -- Birdoswald, I think it was -- and looking down at two of our bold countrymen roaring by in terrain-following mode. I was very proud of them, as they added a "then and now" military flavor to a military day.
