Thanks for the plugs guys. We were all disappointed with the Bloomberg
article, but I guess everyone thinks they're a lot clearer and more
eloquent than what the reporter writes.

I haven't found a use for Black-Scholes in glider flying yet, but my
MacCready theory articles are straight translations from the classic
"optimal portfolio" theory. An investor goes through life with
occasional opportunities (thermals) of varying promise (strength) but
a constraint that wealth (altitude) must never be negative. As you can
see, if you just change the letters you've got the same problem.

Nice one John.

Seems we went through a patch of nasty sink - and are now scratching
around in zero-up hoping it develops into something that will gain us
some altitude (wealth) before the sun gets too low and we have to
start final glide (retirement) from whatever altitude we have. Oh,
yeah and CBs all around us.

If cruise speed were Beta you could optimize between cross-country
speed and the risk of landing out.

Prospects of outlandings are increasing. Make sure you pick good fields
along the way.
