NASA greenlights final assembly of Lockheed Martin’s quiet supersonic jet prototype

Lockheed Martin's X-59 is a prototype supersonic jet designed to be quieter than traditional jets. It can cruise at 55,000 feet and reach speeds of 940 mph. The jet's design aims to reduce sonic boom noise, making it as quiet as a closing car door. It features advanced technology, including cameras and sensors for safe flying without a forward-facing window. NASA plans to test the jet over select US communities to gather data and public feedback.
