current flow is actually from the ground up to the charged cloud, if you slowed the film of a strike right down you will see the light going upwards, not down, as most people think.

Best idea is make sure there is a better ground outside the building than inside, which is why you have lightning conductors on tall buildings, to allow the current to flow up a thick wire on the outside of the building. If you have that sorted you dont need to worry about unplugging anything.

Does the current flow upwards or does the light appear upwards. Maybe the current flow stays static (scuse the pun)

If current flows, surely it can't be static?

The feeler stroke comes downwards, but once it's connected the discharge (the bit you see) goes upwards.
