Sorry for the delay; I haven't logged in for a while.

No, I'm not in Boston any more. After graduating I bounced around in the Air Force for a while and finally landed in Annapolis after getting out.

I'm still casting around for better sources on the keel effect and the stability of high- and low-wing aircraft in general. I was disturbed to find that the Handbook of Aeronautical Knowledge goes rather too far with the pendulum analogy, actually saying that gravity swings the fuselage back down under the wings like a pendulum bob under its pivot. The free-body diagrams on my white board and notes from class don't count as sources, and my S&C textbooks dive right into the stability derivatives without caring much what features of the aircraft configuration produced them. I think maybe one of Roskam's books might address the issue; I'll have to see if I can get ahold of one.
