Really? The paragliding people around here go out and *soar* their
paragliders quite deliberately in thermal conditions. They get some
pretty good altitude gains too. Sometimes they make us glider pilots a

using the winch, if there's no lift in the immediate vicinity of the
airfield we are stuffed...
