NASA moves a step closer to supersonic passenger flights | CNN

A new study by NASA’s Glenn Research Center has looked at the possibility of supersonic passenger jets. Its “high-speed strategy” is mooting commercial flights that travel at up to Mach 4 – over 3,000 miles per hour – starting with transoceanic routes.

In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility. Ground tests and a first test flight are planned for later in the year. NASA aims to have enough data to hand over to US regulators in 2027.

    And you can add 1billion for the previous attempt

    The American government cancelled its SST project in 1971 having spent more than $1 billion without any aircraft being built.[299]
