Another glider crash?

Once, long ago, I nearly got my hand crushed when about to attach a cable
to an ASW20 (belly-hook only). The pilot retracted the U/C when he meant
ot check the air-brakes. The Pilot concerned was a current national
champion, practicing in the glider he was about to fly in the World
Championships. He was also an experienced instructor. His day job was
Airline Captain. Schlecher's practice of putting all the levers on the
left was, in my opinion, not a good idea, it produced more problems than
does changing hands to retract the gear.

Of the 5 gliders I've owned, only the ASW-19b had the gear handle on the
left side. I never liked that and it's never been a problem changing
hands on the stick to lower the gear with the other gliders.

As well as the ASW-20, the other common one with this arrangement is the
Pegase.
