World War Two brought the greatest advances in science in the field of Electronics that the world has ever known, TV, Radar, Sonar, Field Radios, Rescue beacons. The science of guiding airplanes to a safe landing in dense fog. There was and still is no limit to what those crazy little electrons can do. A bombing raid over Berlin near the end of World War Two saw a bombsite button in one of the bombers being pressed and fifty or more planes in the same flight would all drop their bombs simultaneously. A ship at sea could detect an enemy plane or ship many miles away, and to think, this was all done more than fifty years ago.
There were many other advances made during this great war that have never, and because of National Security, may never be known. This hypothesis with a little imagination could be a fact and way of life, just as much as the cellular phone, or credit card, or computer Internets.
