not know of fully-limp wing, apparently.
Flexible kite. Boom stiffening would deposit the Wanner and Bach;
with eyes of Rogallo, the Rogallo wing lives within boom-stiffened
wings. It was synergistic Rogallo leadership that brought a
four-boom bi-conical hang glider kite to the high front of media and
use; the new understanding and trust of the fully limp Rogallo wing let
boom-stiffened sailed wing be seen in a new light; that Rogallo carried
that light to others at a time of need to face Sputnik-changed world is
what let the Rogallo Revolution occur. One may reach a four-boom
hang glider from Lee & Darrah, Bach, and Wanner sans Rogallo; some did;
but the vast large majority of four-boom hang gliders came from the
Rogallo leadership flow as clearly marked in the literature.

hang gliders on up to present time.
