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.

There is a reason the tall masted rigged ships disappeared for regular travel; most people don't want to take a month to cross the ocean in close quarters. Cruise ships are the closest analog to a long haul jet, and are no better to twice as CO2 producing than the airline travel, and the fuel they burn is the lowest grade fuel oil with the worst additional pollution. If you are moving across the ocean, or even just traveling, most people won't be able to pilot their own sailing yacht and take 15-30 days to do it.
