This group? About Apple //s? Let me digress...

People seem to think that a tiny amount of insulation will stop
lightning. "Why are you safe from being killed by lightning inside a
car?" "Uh well, 'cause of the rubber tires - lighting won't have
anywhere to go, so it won't strike." WRONG. It just went through TWO
MILES of air - the best known isulator. An inch or so of rubber won't
stop it now. The fact is, the electrons stay on the outside of the
auto's structure. You can have the window open, and even be touching
the INSIDE of the car and not feel a thing.

In fact, it will! It strikes some point because the conditions (air
density, conductivity, target ground connection, etc.) were good. If
it's good once, it's good twice. Keep away from any previously struck
area.

If you live in the Boston area, I recommend seeing the lightning
exhibit at the Museum of Science. Lots to learn there (where it's fun
to find out!).

Now, back to Apple //s...

My employer pays me well. This, however, does not mean he agrees with me.
I wrote Z-Link & BinSCII. Send me bug reports. I use a //GS. Send me Tech Info.
