Thunderstorm Project: the first field observations of storms
The Thunderstorm Project, a pioneering field study in 1946–47, marked the beginning of focused research based on field observations of storms. The project was a collaboration among four U.S. government agencies: the Weather Bureau (which later became the National Weather Service), Air Force, Navy, and National Advisory Committee for Aeronautics (which became NASA). For the first time, scientists penetrated storms using instrumented aircraft (a fleet of ten Army Air Corps P-61 Black Widows). Results from the campaign formed the basis of our scientific understanding of thunderstorms.
