He Built a HELICOPTER IN HIS CELLAR
WHEN Charles Seibel of Wichita, Kansas, broached his idea for a new-type helicopter to an aircraft company, they laughed at him — said construction alone would take a quarter of a million bucks.
So he retired to his own cellar and started building. At the end of seven months he had an egg beater which flew easily and was cheap to operate and maintain. And it cost him less than $5,000.
Seibel used Ford truck gears and clutches, odd pieces of sheet metal, aluminum tubing, wood and wiring picked up at war surplus stockpiles.
When testing day came, he had no test-pilot so he flew it himself—successfully! And he had never flown a plane before in his life!
“The Seibel S-4 was a two-bladed, single-engine helicopter built by Seibel Helicopter. Designed by Charles Seibel, the S-4 was evaluated by the United States Army under the designation YH-24 Sky Hawk, but would be rejected for service. The S-4B would serve as the basis for the design of the Cessna CH-1 Skyhook, the only helicopter Cessna ever produced.”
