There was an Air Force turboprop fighter prototype (XF-84H) known as the "Thunderscreech." The propeller produced hypersonic frequencies that caused "acute gastric distress" to anyone standing near the aircraft.
Between 22 July 1955 and 9 October 1956, two XF-84H prototypes (S/N 51-17059 and 51-17060) made twelve test flights. Eleven of the twelve flights ended in emergency landings. Sounds produced by the aircraft's turboprop engine caused nausea and headaches among ground crews, earning the XF-84H the unofficial nickname "Thunderscreech." Though the XF-84H was the fastest single-engine propeller driven aircraft ever built, it never approached supersonic speed. Due to poor performance and high maintenance requirements, the XF-84H never became operational.
