Biggest Glider Ever Launched via Winch?

Also have a look at the C-141 towing a QF-106, known as the Eclipse
project or "Dope on a Rope". Doubt I'd want to winch that one!

Has anybody "step-towed" a sailplane? Using a pay-out winch in a
truck, tow the length of the runway. As the truck turns around and
winch operator keeps the slack under control, the glider does a wide
turn. The truck then heads back down the runway, paying out more line.

Jim, Gary Boggs (Oregon?) does the payout winch system with the 2-33, but I
have not seen him turn around, I don't think he has room on the airport for
that.

This was presented at one of the SSA conventions. The video included a
demo of the stability of the system as the F106 pilot was clearly
waving both hands to the camera.

(BTW, you really should come to a convention, you don't know what you
might be missing)
