the problem is that there is no "inbound leg" thus no observation zone
for the finish point... sort of another bug in the Code Sportif ;-)

Huh? The glider had to start SOMEWHERE. So draw a line from the
start to the finish. There's the inbound leg.

Again, I'm making this up as I go along. I'm not an authority on this
stuff. Judy is the USA NAC...
