Planes to fly at 6500 km/h by end of century

Report looks ahead to air transport in the year 2075 and beyond

By the end of the century, planes will be flying in formation, and at five times the speed of sound. This is one of the predictions made in a report released by the UK’s Institution of Mechanical Engineers. But it cautions that this can only happen if governments focus on sectors that boost the economy, such as aerospace innovation.
Innovations that could be reality in 2075 and beyond include commercial aircraft saving power by flying in V-shaped formations; a “flying wing” aircraft design in which the fuselage, wings and engine are merged together; flying fuelling stations; and “scramjets” able to fly at 6500 km/h, or five times the speed of sound.
