For comparison, the concorde it was capable of flying at over 2,500 km/h (Mach 2.04 note). The Boom Overture wants to be the heir to the “most beautiful plane in the world” down to the smallest detail. In fact, it will be necessary to pay no less than 5,000 dollars to be able to travel on board. Like 20 years ago, the device will be mainly intended for wealthy people and business trips.
