You might want to talk to the crew of that 757 or L1011 or whatever it was that crashed in Souix City(?) a few years back because it lost ONE of THREE engines and immediately went ballistic.

Ian I would think that in the case of airliners they have so many redundant systems that if one goes down they have two or three others to continue with, so there is no emergency situation in there case.

I will take reduncancy ever day of the week compared to a single CB circuit albeit it I have parallel master switch circuit breaker's but I do not intend to reset one as long as the other is working :>)   I know we are not changing anyone's veiws on CB vs fuses, but it has been an interesting dialogue.   Bernie
