5 vezes a velocidade do Som!
...E de Nova Iorque a Sidney em 2 Horas e meia!
Eis o que a NASA está a planear construir, um Avião de Passageiros, que vai revolucionar o Transporte Aéreo:
New York to Sydney in just 2hrs 30mins: Nasa to develop 'hypersonic' passenger jets that travel at five times the speed of sound
By Daniel Bates
NASA is planning to build hypersonic jets that will fly through the Earth’s atmosphere and slash flight times around the world to a few hours at most.
The US space agency wants to manufacture a craft that would travel at five times the speed of sound and bring in a new age of aircraft akin to a turbo-charged Concorde.
Travelling at such speed would reduce the flight time from New York to Sydney to around two-and-a-half hours, from the 21 hours it is now.
The project is thought to be aimed at making a reusable aircraft that could fly to Mars but, as with previous space technology, it could have a huge impact upon passenger transport too.
