Title : Hyper III on ramp with single-piece pivot wing installed & Princeton sailwing on ground, with Danial C. Garrabrant
Caption :
The Hyper III's shape provided too little lift to land without some type of deployable wing. The single free flight was made using a simulated one-piece pivot wing, which was attached to the upper surface of the fuselage. This used a wing kit from an HP-11 sailplane, which was assembled by Daniel Garrabrant (shown in the photo). Another possible wing was the Flexible Princeton Sailwing. The piloted Hyper III flights were to be made using an SA-16B Albatross seaplane as the drop aircraft. The Hyper III would be carried under the SA-16B's wing on a drop-tank rack. Flight Research Center Director Paul Bikle asked NASA Headquarters for permission to exchange the Center's C-47 for the SA-16. Headquarters turned down this request, effectively ending the possibility of Hyper III flights with a pilot on board.
