It’s now been two decades since the era of supersonic commercial flight ended with Concorde’s final touchdown in an airfield in southwest England.
In recent years, numerous pretenders to the throne – supersonic, hypersonic, hydrogen-powered, with anti-boom technology – have been whizzing round, conceptually at least, but many of these projects promising seamless super-fast travel have instead stalled, sputtered out or hit delays.
Now a European hypersonic startup is having a go, promising enticing journey times such as Frankfurt to Sydney in 4 hours 15, or Memphis to Dubai in 3 hours 30.
The Destinus concept is hydrogen-powered flight at five times the speed of sound, cutting flight duration to less than a quarter of current commercial air travel.
