This is actually an interesting problem because you'd think the skin of an
aircraft would be effectively a faraday cage and that all points along it 
would be equipotential, but in fact that's not really the case.  Lightning
strikes can cause huge skin currents which inductively couple into 
electronics inside.

is an interesting introduction to what goes on, it's a lot more cool than
it looks at first glance.
