United Airlines Plans For Supersonic Air Travel By 2029

Startup company Boom Supersonic says the planes haven't been built yet, but they will fly at 1.7 times the speed of sound.

United Airlines is trying to bring back supersonic travel. It announced it's buying 15 new jets from a Denver startup. The jets would carry between 65 to 88 people at a speed of Mach 1.7 and it would cut flight times almost in half.
