Glossary of the book:
G
Glider. A heavier-than-air aircraft that is supported in flight
by the dynamic reaction of the air against its lifting surfaces,
and whose free flight does not depend on an engine.
\============
[[Comment by JoeF: "supported in flight" would be a stretch during fall under collapsed canopy; when PG is collapsed, then it would be a stretch even to call such a parachute at that time; when a soaring parachute is inflated and gliding, then such would be gliding kite system and thus a glider mechanically; but when the system is collapsed and falling, then gliding and kiting fairly well nearly zeros out; piloting nearly zeros out at such collapsed time. Soaring parachutes in collapsed fall sometimes reach for a reliable rescue parachute that does a better job for arresting the fall .... the fall that has killed too many humans. Trouble is, collapse of the soaring parachute occurring in the zone where an otherwise dependable parachute would be nice IF ENOUGH VERTICAL DROP would be available; counting surprise, reaction time, and successful deployment of the rescue chute: there ends up being a proven Zone of Nothing Helps; parachutal is not available in such zone for the collapsed soaring parachute. The collapsed wad PG at such time is not gliding helpfully, is not kiting helpfully, and might thus be considered as non-aircraft, non-glider, non-parachute, but a falling mass in the special zone where rescue parachutes won't open on time. Sad thing is: Ordinary airs have turbulence that will steadily collapse soaring parachutes within the zones implicit in RM's described
Paraglider Dead Man's Curve or
PDMC ] Does the FAA ever want a device such as a soaring parachute even to be considered as an
aircraft within their auspices? A device that becomes too often while in the air a device that cannot be piloted with authority and that too often becomes a non-glider, a non-kite, a device where not even a rescue parachute will save the day? A device that has a very substantial PDMC? States having an interest in keeping citizens might take a another look at what is going on in the PG world. ]]]

Inflatoplane is designed to stay inflated.
Kytoons are designed to stay inflated.
