Hang-gliding is a technique of unpowered
flying using air currents, perfected by US
engineer Francis Rogallo in the 1970s. The
aeronaut is strapped into a carrier, attached
to a sail wing of nylon stretched on an
aluminium frame like a paper dart, and jumps
into the air from a high place, where
updrafts of warm air allow soaring on the
`thermals'.
