"The ability to navigate was kind of limited," said Lee Person, a retired NASA research pilot.
His experience has left him adept at using research, pilot testing and other marketing tools in making creative decisions.
Drawing on continued research, pilot projects are being developed for sites in South Africa, Ethiopia, South Sudan, Malawi and Burkino Faso.
In 1955 he became a civilian research pilot for the National Advisory Committee for Aeronautics (NACA), later the National Aeronautics and Space Administration NASAA).
In 1955 he became a civilian research pilot at the Lewis research centre of the National Advisory Committee for Aeronautics (Naca), the forerunner of the National Aeronautics and Space Administration Nasaa).
By the late 1950s he was flying big, twin-jet-engined A3 bombers from aircraft carriers and was also working as a research pilot.
He is in his fifth year of teaching He is currently involved in a national research pilot to develop a new and authentic KS3 PE curriculum with the Youth Sport Trust and the TOP Foundation.
In a widely distributed NASA video for pilots, made in 1997, William J. Rieke, a research pilot at what was then the NASA Lewis Research Center in Cleveland, warns that if ice has caused the tail to go into aerodynamic stall, and it is misdiagnosed as a wing stall, "you and your passengers could be history".
Harry Verstynen, the chief research pilot at NASA's Langley Research Center, says his initial reaction to the windowless cockpit was "not only 'No' but 'Hell, no!' "But now, having flown in an X.V.S. -equipped plane, Verstynen says the system "has distinct advantages over a window, which works only in the visible spectrum".
