One would have to wonder, though, just how much skewing all of that metal and magnetic fields from other instruments might have impacted the problems for those airborne loops as well -- even realiziing that at the time this had to be known and somehow taken into account. Then, too, when you're piloting a B-47 and using a loop to zero in on KGMB, all you need is an error of a handful of degrees and you've missed, to that may have been as much of the problem as anything - even our standard of error would have been too much for WWII navigation.
