They had a lot of, firstly there was a lot of maps. Map drawing - awful, you know? Because the planes are flying and you know, you had to have maps for them. That was one thing. The other thing was simply that the structure inside the guns changed. It got better and better and better. So we had to make drawings for this other unit, who could take those drawings and make the changes inside... inside the machine. But there was a… one very funny thing happened. I was doing these maps, you know, about this long and this deep and all that stuff, and I was second, I was not an officer, I was like a second-in-command, whatever it was. Anyway, so one day, there was people were coming from a very high… hierarchy and they were all majors or generals or what not. So they came up to the room where I was working with a friend of mine on the maps, you know? And it was very funny. This one lieutenant looks at my drawings and he says, 'Hey, looks like little Kandinskys'. Well, he knew art, that's for sure. And that funny part of it was that I know I was doing it like that because if you look down from high above, the whole thing becomes an abstraction, you know? Really. So this guy, this lieutenant says, it looks like an abstraction, you know? And they thought it was beautiful drawings. But I know what I was doing but I wasn't going to tell him that, 'Yes, you're right because…' you know? Well, that is one of those incidents, you know, when you're art. In a good position.
