Dear God!

Didn't anyone pay attention to physics lessons in high school?

Actually, I skipped a lot of physics & math lessons in high school, to go
soaring with a friend from my class. ( I guess you figured that out by now
;-)
We had a math teacher who eventually figured out the connection between blue
skies with cumulus, and the two of us being absent from class. One day he
called the gliderport, just to let us know what chapters to read for next
week. -I was the unlucky one who picked up the phone...

Happy soaring, and safe pullups to exactly the same altitude no matter what
mass you fly at,
