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.

    They’re promising

    I guarantee it will be louder than that. Unless the flight path is directly over a senator’s house or an historic golf club (where donors play), it will be too loud.

    Literally make the flight path over the richest part of town or I won’t believe it.

      NASA has no control of flight paths. The FAA also doesn’t specify sonic-boom allowed flight paths. They just outright ban it (with a few exceptions) for any boom that could reach anywhere in the US.

      FAA also doesn’t want to deal with people complaining about sonic booms like they did back in the 50s when this all started (they received tens of thousands of complaints) so they have an interest in making sure NASA lives up to their promises.
