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.
