Edison, Thomas A.
OCT 28 1929
At the right is shown a replica of the first incandescent electric light invented by Thomas A. Edison. Below, at the left, are Henry Ford, Mrs. Ford, President Hoover, Mrs. Hoover, and Thomas A. Edison arriving at Detroit to join in the semi-centennial celebration of the aged inventor's great gift to mankind.
Blazing in Edison's honor were the brilliant runways of the night flying system of Airport Lighting, Inc., installed at Grosse Ile Airport.
Edison viewed a working replica of the system in the Pageant of Light on Washington Boulevard, Detroit's "Fifth Avenue".
Submerged lights, at 100 foot intervals, are set flush with the line of three runways at the airport.
A windvane automatically controls the lighting of the proper landing runway.
Leading pilots, testing the system, declared it to be the most satisfactory yet presented for night flying.
