Project Mogul was a top secret project carried out by the US Army Air Forces involving the launch of stratospheric balloons carrying sensitive microphones, whose primary purpose was long-distance detection of sound waves generated by Soviet atomic bomb tests. The project was carried out from 1947 until early 1949. The project was moderately successful, but was very expensive and ultimatelly was replaced by a network of seismic detectors and air sampling for fallout.
