Were they the model where the entire front of the aircraft separated?
All F-111 models had a ejectable crew capsule. None had ejection seats.
Since the plan was to be operating at Mach+, ejection by traditional methods didn't give the crew much of a chance to survive.
There's a story of one pod landing, well, hitting, at over 30G's. Both crewmen survive with maybe some broken bones, including a vertebrae or two, but were able to walk out of the hospital.
