This weeks headache.

Have fun

l have no idea what it is...perhaps a wing designed for Newbie Wing Walkers

1st clue
"the airplane was so easy to fly that someone who had never flown a plane before could learn to maneuver the ?????????? in thirty minutes"

It's the Nemeth Parasol...





During the test flight, Nemeth stalled the craft mid-air and let the disc wing do the work of a parachute. The demonstration was a success: with the motor off, the wing stabilized the aircraft, and it came down ?almost vertically? to a gentle landing, according to a 1934 report from Popular Science. The Nemeth Parasol became the first round wing design to maintain consistent flight.

Well done it is.
