What discharges an airplane of static electricity in a electric storm when it is flying. I assume the charge is on the out side of the plane but when does it get discharged, or does it occur at landing?

Thanks,

I think the answer is that the charge is dissappated through the air, which is a somewhat better conductor than people think, particularly if there is a high moisture content. The charge will indeed be on the outside of the plane as it is a conducting shell. It will accumulate until there is sufficient potential to discharge. It will certainly discharge to ground once it is in contact there.
