Hydrogen-powered Hypersonic Aircraft Capable of Flying At Over 6,000 km/h Could Be in Our Future

Two projects are on the agenda at Destinus: a 25-seat jet (code name Destinus S) and an airliner for carrying 400 people (Destinus L). The idea is to fly up to Mach 5, ie, five times the speed of light, or over 6,000 km/h.
