Meditation over an experiment in 1963 first half of year or earlier.
Actual day of image
was BEFORE the publication date.
Date of photo is sought. Anyone?
Another, date needed, not
known, but help is requested. Thanks. An article in Ryan Reporter
does not state the date that the
Yuma test was done.
The near-standard control A-frame used in hang gliding over 50 years ago in 1908
is assisted to hold the payload by a frontal A-frame. Also a fifth rear bar
might triangulate to stabilize the payload. Army-Ryan test:
John Worth had already established the A-frame for hang gliders for the
NASA environment on the flexible wing; then Ryan
used the similar arrangement to hold payloads.

Exact date of the different shot below is invited by willing research volunteers:

step through the offered images.
See some of the Ryan Flex Wing Hang Gliders with A-frames to control the
position of the hanging payloads.
