re: The title of Bill Lear's autobiography was "They Said It Couldn't Be Done"
Thanks for that thumbnail, Larry. I had a sketchy knowledge not much above the fact of Lear's existence, and I'm a full paragraph better informed.
Observing the fluid ease with which you produce posts like encyclopedia entries, gets me to thinking about how the undifferentiated mass of the Zone's message database can become different things if indexed different ways. In particular, the accumulation over time of expository posts by you and Gary and Tom and others could be indexed to form a (somewhat eccentric) encyclopedia about aerospace topics. Index the many posts about Mars and you'd have an adhoc encyclopedia of planetology. You get the idea. That's a notion I'm going to ponder some more.
