I've wondered if the best way to launch is by gravity, a weight falling into a mine shaft and attached to the glider by a cable. If you have a supply of water then the weight is by filling a tank. At the end of the launch you dump the water, pull the much lighter tank back up, then refill it. Given enough room you could have a circular airfield round the mine shaft. The only energy that you need to supply is to retrieve the tank and cable. A few things to sort out but it's a start I like it! Just get M C Escher to design the airfield and Bob's Your Uncle! -- Martin | martin at Gregorie | gregorie dot org
