That makes sense....my background is Navy so the whys and wherefores of the US Air Force often escape me...
Personally, I’m a big fan of the ‘Varks...coolest ejection system ever invented in my view, although I’m not sure I’d like to test ride it.....
The F-111 is almost as much a product of the Navy as it is the Air Force. It began as a joint fighter, before the F-14, but disagreements on performance and mission characteristics caused the Navy to bail and start work on the F-14.
