Please name one accident of a glider with auto hookups that could have
been prevented by a positive control check. I sure don't know any. A
seized bearing will be detected by simply moving the stick. In all
gliders I know there is no scenario of control failure that would
necessitate a positive control check for detection.

You are making a slippery slope argument. Should we mandate annual
stress tests of wings in the name of safety? Overhaul all tost
releases every 100 cycles?

A "clueless" or "ham-handed" helper is no excuse - it just means you
were in a rush or trusted someone you should not have (or that you
didn't properly train them).

Even with auto-hookups, fittings can come loose, bearings can sieze,
and controls can fail.

Simply seeing the hookups slide together does NOT ensure that the
aircraft is functioning properly!
