Has anybody ever tried to launch a glider purely by gravity without the
aid of any other means? Ok - pushing it over a cliff would be one way.
I am more thinking of a steep incline, which a glider could just roll
down, i.e. a slow glider flying and a steep straight mountain road.

There's a video somewhere on the 'net of a PW-5 being launched exactly
that way, rolling down a steep, smooth grass slope. 2 or 3 people push
it at first before peeling off as it gains speed and then lifts off into
the slope lift. I think this was filmed in Poland.
