Now Doug, don't go making fun of model plane designers,

Sorry, I was not meaning to belittle any model airplane designers. Just
pointing out that a wing keel for a sailboat fulfills a rather different
function... several, actually!

... remember
"The Flight of the Phoenix", (Shute, IIRC). ;-) One case where
the movie was just as good or better than the book, a rare event.

Never read the book, the movie was pretty good. We'll have to ask Peter
W about which is better...
