Yes Patch! As I recollect when I was a young lad, pulley launching worked well up to a point on one occasion, when the F100 ute towing cable and being driven back towards the Kookaburra glider on launch, was driven over the cable rising off the ground as the Kooka soared up the launch. The cable snagged the drivers side door handle. Yes, there was a lot of sawing going on that day >> however, not too much soaring as it was stable that day as I recollect. Cheers Roger Druce

Subject: Re: [Aus-soaring] Pulley Launching Michael, We used a reverse pulley system at Bacchus Marsh for some years back in the 60's. Great system, on one day we launched I think nine gliders before the first one landed, no lift conditions. Very fast very simple and safe.
