At nearly the same time, in September 1940, a British delegation led by Henry Tizard, chairman of the Aeronautical Research Board, came to the United States to share techno logical information, including the cavity magnetron.
Without Brummie know-how there wouldn't be microwave ovens or radar because the cavity magnetron was invented here.
Stories include the invention of the B-29 Superfortress (which would drop the atomic bombs on Japan), the Hedgehog (a ship-mounted mortar launcher), and the cavity magnetron (a miniature radar).
