The future of ultra-fast passenger travel
Today, aerospace startups and giants alike chase ambitious dreams of passenger flights that exceed the speed of sound, connecting continents in mere hours or even minutes.
Today, aerospace startups and giants alike chase ambitious dreams of passenger flights that exceed the speed of sound, connecting continents in mere hours or even minutes. Concorde, cruising at twice the speed of sound (Mach 2), ultimately failed economically due to excessive operating costs, poor fuel efficiency, and regulatory restrictions on overland supersonic flights. Detailed analysis suggests Starship’s fuel efficiency per passenger-mile could be near 30 kg/100 km/passenger of propellant (methane and liquid oxygen combined), comparable with hypersonic jets, potentially making rocket travel economically viable within luxury and premium tourism segments.
