Radar, as the name implies, was developed for rangefinding and
targetting in this program but the first principles upon which it is
based were not. Radio experiments in the 20s and 30s discovered that
radio waves bounced off of storm fronts. It was weather research and
a cool new toy called radio, not a need to track aricraft, which
brought us radar.
