Standard operating procedure: pick a field, pluck off the wings,
put glider in trailer, go home. Also many gliders have "get
out of trouble" engines, but they expect not to use them.

But the point is not whether gliders are practical means
of transport (they aren't), but whether you need engines
to go up. (You don't - unless you count the sun as an engine
:) )
