I got into LA about 5 PM, and American managed to not lose my luggage this time. Henry Vanderbilt called me while I was grabbing some stuff at Trader Joe’s for dinner, and apparently I’m now scheduled to be a speaker tomorrow, if I can drive over to Phoenix in the morning sans incident. And think of something non-useless to say.

Actually, if Henry is reading this and wants to update the program, I’m going to talk about one of the most misunderstood and ignored (at least by the main aerospace establishment) topics that have kept us stuck on the planet — marginal costs.
