"Bill Daniels" s comments read:

I was shown a gadget just for this sort of thing made of PVC pipe. It was
essentially a tripod with a 2 meter horizontal pipe along which the wing
would slide as the glider started its roll. It was intended for airtow but
the thing would work with a winch.

Surely this situation normally occurs when retrieving as well as days
when the operation is normally closed. I've heard a tale about a coke
can and good blast of prop wash being used to get the wind up. Sounds
like asking for trouble ...
