Run Forrest...Run!
When I was a wee laddie wearing shorts, I thought it would be a good idea to press on (C-175), and take the most direct route below a CB. This proved a very bad idea.......Swore that if I got through that I would never go near another one.
Then a few years later whilst operating from Nadzab to Pom entered a CB at night(no Wx radar in a Twotter)............Flight idle FL 150 still going up @ 1500fpm.
Moral is don't go anywhere near the B'strds.
I now fly a nice new smelly NG737 and still don't go anywhere near the mongrels.
