PN, there was a special CB pulling tool used in the F4 and I don't recall any fightergator ever taking a 'nav rule' on board an F4. I can't remember the drill for double TRU failure in the Vulcan, but most circuits had fuses rather than C/Bs.
I think that it was the Swissair fatal accident near Halifax which highlighted the issue of C/B resetting? Since then, an unexplained C/B trip is never routinely reset in civil-certificated aircraft.
