Default Auto-Towing - why is this not more popular?

I wrote an article for the UK "Sailplane and Gliding, Dec 2013 / Jan 2014". Title was "The Expedition Glider Pilot's Guide to Launching".It covered bungeying (of course) and also what I have called "modified auto-towing". The modification is the use of pulleys (ground and car) to give a 2:1 or 3:1 ratio. The car travels at 1/2 or 1/3 of the glider rope speed ( and distance of course), with much less bumping around for the tow car (and occupants), and all very civilised. The car can continue to pull in the rope ( against the drogue if you wish) thus preventing the problem of long ropes falling all over the countryside. It is more akin to a winch launch, rather than a standard auto or simple reverse pulley autotow. If you send me an email on I can send an electronic copy of the article (for personal use, you would need my and the Sailplane and Gliding Editor's permission to publish further). Pete Whitehead
