Why is commercial air travel still the same speed it was 60 years ago? And will it ever change?
In: Technology
Commercial jets cruise just below the speed of sound.
Going any faster requires a supersonic aircraft, which radically changes the aircraft design and fuel consumption and is much more expensive.
There were some forays into supersonic passenger travel, but the cost was never competitive and the earth-shaking sonic booms of Concorde jets leaving the airport were very unpopular.
