Built by a Swiss startup in Spain, Destinus is a hydrogen-powered supersonic aircraft that could potentially reduce flight times, while improving efficiency.

The speed of sound varies depending on different factors, for example, the speed of sound underwater isn’t the same as the one on the ground.
It even changes depending on altitude, but the consensus is that the speed of sound equates to 1,235 km/h, so presumably this means Destinus could be capable of flying at least at that speed.
That’s nowhere near as fast as the Concorde, which was in fact nearly twice as fast, but still faster than any major airliner today.
