Extreme Science: Science in the Danger Zone
Inventors...scientists...researchers...daring thinkers the world over attempt the impossible and take extreme risks - even when it means putting their own lives on the line. These are their stories.
A Sample
Rocket Man
Harold Graham had twenty seconds to prove the worth of the bulky contraption on his back. Twenty seconds
to blast skywards, scoot a short distance, and land safely...or die trying.
Strapped to Graham's back was a wild and dangerous
device. In some ways it resembled the scuba gear carried by divers. It had two tanks and a system of hoses and nozzles. But instead
of guiding Graham below the ocean surface, this device fired him aloft.
The contraption was called a rocket belt. It had been
invented by Wendell Moore, an engineer who worked for Bell Aerosystems in the 1950s. Mostly made from spare parts, the rocket belt
had two tanks filled with hydrogen peroxide. The fuel was fed over a fine metal screen which changed it to steam. When the steam was
forced through a pair of nozzles, it unleashed enough thrust to shoot a person upward.
Graham, a young engineering student, volunteered
to test the device. On
When he was ready, Graham
engaged the rockets. A blast of steam erupted from the tanks with an ear-shattering screech. Graham slowly rose up out of the cloud
of steam. High above the ground he adjusted the throttles and zipped ahead a short distance, hovered for a moment, then gracefully
lowered himself to the ground.
As brief as it was, Graham's flight made rocket history and proved that free-wheeling human flight was entirely possible.
