Admittedly that needs a dedicated team (winch driver, cable truck

Sure, but from what I see on r.a.s, winching seems to be making some
headway in America.

The minimum launch requirement is three people: winch driver, launch
marshal/wing runner and the glider pilot who, if needed, can tow out the
cable he launches from. IOW, not much different from aero towing except
that nobody in their right mind or half out of it would ever start a
winch launch with a wingtip on the ground.

The cross wind on this thread has blown us on too an entirely different subject, while worthwhile. Course correction: Anyone know the cause of the turbine failure first mentioned in this thread? How much damage was done to the airframe when the engine failed? Have the problems of not starting at altitude been understood and resolved? Has anyone had these failure and care to comment?

High altitude starts - see my earlier replies. The M&D jet is not intended to be started above 10,000 feet asl according to the manual and it starts fine up to at least 9,500 feet asl in my experience as long as a fuel that suits the climate is used. Mine was very unreliable hot on high in SA with Jet A1 and unreliable in cold UK weather on standard diesel but worked 100% until sold in both situations on premium synthetic (gas-to-oil)/mineral diesel (which, for clarity, is not bio-diesel). It was someone from the JS factory that told me a couple of years ago to use Shell V-Power Nitro diesel when I asked for help while in SA as that was what they used.
