Lol at the above – Richard I hate you I shouldnt have come up that weekend just gone! Id managed to kerb my addiction and now im dreaming about flying her again 🙁

Now that’s scary! In some ways it doesn’t seem like two minutes ago 😮 still a fondly remembered day 🙂

He cant help it in all fairness – He is afterall a yorkshireman

Not after calling her a glorified wind farm you won’t….

Im sorry but I couldnt resist 😀

Not entirely sure – However the link speaks for itself

The small amount of O2 at the Operational hight of a scramjet would pall in comparison to the compression of the engine when scooping it up at mach 10 :diablo:

NASA flew a third version of the X-43A on November 16, 2004, achieving/maintaining a speed of Mach 9.68[2] at about 34,000 metres (112,000 ft) altitude [3] and further testing the ability of the vehicle to withstand the heat loads involved.[4]

This would be the one 🙂

Wikipedia X-43

AFAIK there were a number of interesting prototype air breathing engines in test at the moment.

I believe the scramjet holds the world record for airbreathing flight at mach 10+
