In my ramble about lightning yesterday, I mentioned a more detailed explanation of the phenomenon would probably contradict the simplified magazine piece that told me lightning always travels from clouds towards the ground. A few folks on the forums have argued back and forth a bit on this, but the How Lightning Works article on Howstuffworks supports the idea that it can indeed travel up, although it doesn't sound like a very common occurrence (this is all relative, as the Maxim article that got me started on this also points out that the earth is struck by lightning approximately 100 times a second). This page of the article (thanks Aaron) points out something mentioned on the forums here as well: that in some sort of Alanis-shattering coincidence, one of the types of lightning that travels upwards, the existence of which I was pondering while flying above the storm in the BlueJet, is called (drum roll) Blue Jet Lighting. No, really.
