Safety measures onboard include batteries, thermal backup systems, and an emergency restart system using hydrazine fuel, ensuring the aircraft can recover from power loss during flight.

Designed for high-altitude flights up to 55,000 feet, the aircraft features a comprehensive life support system, including oxygen delivery and a G-suit, to protect the pilot in extreme conditions.

The pilot, Nils Larson, highlights the importance of trust among the team members—engineers, technicians, and crew—to ensure the aircraft's safety and successful inaugural flight.

Extensive safety systems, such as the Flight Test Instrumentation System (FTIS), record over 60 data streams with more than 20,000 parameters, accumulated through hundreds of days of ground testing.

Additional safety features include an ejection seat and canopy adapted from a U.S. Air Force T-38 trainer, providing emergency escape options during flight.

The X-59 employs a digital fly-by-wire system with multiple backup computers and redundant electrical and hydraulic controls to enhance stability and safety during flight.

NASA's research aims to gather data to establish noise regulations for future commercial supersonic flights and demonstrate the aircraft's safety and viability, addressing previous concerns about sonic booms.

The aircraft is engineered to produce a quiet sonic 'thump' instead of a loud boom, making supersonic travel more acceptable over populated areas.

Meanwhile, China's Comac is developing the C949, a supersonic jet expected to carry 28 to 48 passengers with an 11,000 km range, aiming to enter service by 2049 and compete with NASA's designs.

The C949 is projected to reduce transatlantic flight times from London to New York to less than three hours, promising a significant leap in travel speed and efficiency.

The aircraft's first test flights will include low-altitude runs at about 240 mph, focusing on system safety and integration, with the goal of eventually enabling faster, quieter commercial travel.

NASA's X-59 is a pioneering quiet supersonic aircraft designed to fly at Mach 1.5, with initial low-altitude safety tests scheduled at US Air Force Plant 42 in California to verify system integration before progressing to higher speeds.
