Sorry, I can't resist telling a story:
When I was young we were going camping (great ol' days). Once we hit the occassional summer thunderstorm. Mom freaked out on the thunders so dad suggested sitting in the car. That puzzled me because the car was made of metal. What if the car got struck?
Then I was explained a couple things about electrons: They like the most easy and quick way possible out of dodge, and they hate each others guts.
So, when a lightning strikes something like a car or an airplane, that's made of metal, the electricity refuses to touch anything else unless it has to to get to the ground.
Also, because electrons hate each other
(in physics because they have the same.... [oh my god do I know this word in english?] Anyway because they are all negative and they.... [I think I need to get some sugar, brain functions not right , what's the opposite of attract?] Oh hell I give up on the physics rant, they just hate each other ) they try to stay as far from another as possible. So they stay on the surface, or skin of the car or airplane and never go to bother anything on the inside, like our little sorry bodies.
Of course there are other things to consider in a plane. Antennas might get struck, frying everything electrical, engine stopping (
hey I'm gliding, good I don't have any electric actuators on the controls), or fuel igniting
But I think these are slim chances. What would you be doing in a thunderstorm anyway? The least of your troubles would be the lightning.
I just realized... I had a great time writing down those silly things at 5 in the morning. Hope you enjoy!
