Today we’re celebrating the 70th anniversary of supersonic flight, which is faster than the speed of sound! For 70 years, barriers have been broken as planes loudly flew supersonic. Now, we’re working to make history again in a quieter, revolutionary way.
Our supersonic research has brought us ever closer to making commercial supersonic flight over land a reality. That would mean you could travel from New York to Los Angeles in 2 hours.
These efforts have dealt with research in several areas, including the use of cutting-edge visualization technology to study shockwaves, the use of F-15 aircraft to examine methods for improved cruise efficiency, the integration of displays to help pilots monitor the audial effects of supersonic flight and the impacts of the environment on sonic booms.
