Also look at the cockpit area.The F111 was the only US aircraft that had an ejection capsule.The pilots sat side by side and the whole cockpit area was blasted frome the fuselage,and floated down like a space capsule.Had floatation bags for water landing,even the control stick could be used as a bilge pump.
B-1A had it too but there were only two (I think) built. It was cut as too expensive for the 4 man crew. I was on one once at Rockwell.
