X-59's engine started for testing for the first time. NASA's Quesst ("Quiet SuperSonic Technology") mission recently reached a key milestone as it began testing the engine that will power the X-59, an experimental supersonic aircraft developed by Skunk Works for NASA's Low-Boom Flight Demonstrator project.

NASA engineers fired the engines on the X-59 research aircraft in advance of planned test flights to determine if the aircraft can reduce sonic booms and make supersonic flight over land quieter.

NASA has marked a major milestone in its creation of an experimental aircraft. Biden might want to crimp Iranian and Russian oil revenue once he doesn't have to worry so much about gasoline prices at home.

NASA and Lockheed Martin’s Skunk Works subsidiary have started the first testing phase of an engine that will power the X-59 experimental aircraft being built to achieve quiet supersonic flights under the space agency’s Quesst mission.
