@andranator2 Hey there!

@ceruleanspark Do you want to hear my pilot fact of the day?
Saturday, 03-Dec-11 20:07:08 UTC from web-
@andranator2 Sure thing! I could do with some education

@ceruleanspark todays pilot fact is how airliners can fly through a thunderstorm without worrying about lightning

@andranator2 Cool, I'm flying to NY next week, so this might be completely relevant.

@ceruleanspark an aircraft like that employs a design element know as a Faraday cage to protect it. What that means is if it gets struck by lightning because the exterior metal surface is one continuous skin and is separated from the interior by a non-conductive layer, the charge from the lightning strike is dispered over the entire surface of the aircraft and since there is no conductive joint between the skin and the interior components it doesn't effect anything on the inside. The avionics (flight computers) are also protected in this manner. That is why airliners can fly through thunderstorms.

@andranator2 I always thought it was because there's no link between the plane and the ground. This makes way more sense.

@ceruleanspark The ground actually has very little to do with lighting, it's all about the differnece in charge. Lightning occurs due to unevenly charged portions of the cloud. Because the cloud is so unstable you get pockets of positive and negative charges and they discharge as lghting to even out the charges. That's why lightning can strike in 3 ways: cloud to cloud, cloud to ground, or ground to cloud. The ground can actually strike a cloud it's very cool. And that's how lightning works.

@andranator2 I was never very good at physics. Can you tell?
Saturday, 03-Dec-11 20:23:48 UTC from web-
@ceruleanspark That's fine I'm very good at physics so I'll cover that gap in your knowledge for you. I have to get back to work now, we"re cutting down a tree so they need me. I have to go. I'll be on later.

@andranator2 Good luck with that. See you later!

@ceruleanspark Damnit, i keep forgetting who's IP is whose. Which one was yours?

@tenmihara Y'know I think I have dyndns set up. Serrio.dyndns.org should probably work.
