Someone posted these scanned S&G PDF files to the winchdesign group
today. I'd seen one before and had been looking for one of the
others. They may be posted elsewhere and familiar to some
contributing to this thread. So I've made them more widely available.

As some who had a ground loop many years again on a winch launch
(tall, damp grass 12" and inexperienced wing runner that didn't run,
but dropped the wing on all out), I'm with the hand on release. Wing
down, get off.
