In my case the winch driver was me an impoverished student and lowly member of the gliding club who spent an entire day winching (and mending cable breaks) in return for a quick circuit in the K7 at dusk.
Often got : nah it's too dark now.
Gave up gliding and G Club membership soon afterwards.
Me too. I often wonder how many folk were lost to gliding through that sort of inexcusable experience.
