In launch event on Friday, agency shared plans to test over US cities to see if it’s quiet enough by engaging ‘the people below’

Nasa has unveiled a one-of-a-kind quiet supersonic aircraft as part of the US space agency’s mission to make commercial supersonic flight possible.

In a joint ceremony with Lockheed Martin Skunk Works in Palmdale, California, on Friday, Nasa revealed the X-59, an experimental aircraft that is expected to fly at 1.4 times the speed of sound – or 925mph (1,488 km/h).

The aircraft, which stands at 99.7ft (30.4 metres) long and 29.5ft wide, has a thin, tapered nose that comprises nearly a third of the aircraft’s full length – a feature designed to disperse shock waves that would typically surround supersonic aircraft and result in sonic booms.

    Wasn’t somebody developing an engine with two modes, an air breathing one and a rocket one?

    Because suborbital flight is nowhere as hard as reaching a stable orbit (even LEO) and if your vehicle can operate in air-breathing mode most of the way up it needs not be anywhere as heavy since it doesn’t need to take that much oxidizer along.

    What I’m talking about here is a problem around the same order of complexity as an intercontinental ballistic missile, not the same order of complexity as a space shuttle.

      S.A.B.E.R. was the project name I believe, synergetic air breathing rocket engine.

      Basically you intake air at lower speeds and transition to LOX when necessary.
