Yes VC portfolio company, Boom Supersonic, unveiled the design of its supersonic passenger jet. United Airlines will be one of the first to take it to the skies. It won’t burn fossil fuel because its engines are being designed for 100% sustainable aviation fuel (SAF).

Nearly two years after rolling out ts prototype supersonic demonstrator, the XB1, Boom has unveiled a major new design for its much anticipated Overture airliner, which will fly at twice the speed of today’s subsonic commercial jets and is expected to carry its first passengers in 2029.

According to Kathy Savitt, president and chief business officer at Boom Supersonic, the refined design is the result of around 26 million hours of software simulation, five wind tunnel tests, and 51 design iterations.

The aircraft, scheduled go into production in 2024, will fly Mach 1.7 over water with a range of 4,250 nautical miles and have capacity for 65 to 80 passengers, say the team at Boom.
