I keep seeing the World of Warcraft mentioned here. After I figured out it had to do with a game, I stopped reading that thread, but it keeps showing up and I always think of P-51 Mustangs, B-24 Liberators, B-17 Flying Fortresses, and P-38 Lightnings. Sometimes ships like battle ships, cruisers, and destroyers cross my mind, but usually it's the airplanes.

And why it's always warcraft from WWII, I don't know. It always amazes me how much memory a human brain has, but I'm still considering having mine upgraded with a little more disk space. Some of my files from the 1930's are getting a little fuzzy.
