An English inventor who developed the technique of spin stabilization
. Even following William Congreve’s work, the accuracy of rockets was not
much improved. The devastating nature of war rockets was not their accuracy or power, but their numbers.
During a typical siege, thousands of them might be fired at the enemy. All over the world, rocket
researchers experimented with ways to improve accuracy. It was Hale who thought of the idea of allowing
the escaping exhaust gases to strike small vanes at the bottom of the rocket, causing it to spin like a
rifled bullet in flight.
