Synopsis
For more than half a century aeronautical engineers have been working on the dream of hypersonic passenger flight.
London to Sydney in four hours is an often cited goal.
In Discovery Gareth Mitchell looks not at the past history of hypersonics, but at current developments.
He meets engineers working on the propulsion systems and developing new materials specifically for hypersonic flight.
Technologies which could be one applied to space craft as well as aeroplanes.
Hypersonic Flight
Could hypersonic flight become a reality?
Work has begun on a passenger aircraft that could go further and faster - flying from Europe to Australia in four hours. Will it ever become a reality?
