NASA will today attempt to test fly it’s Mach 7 ‘scramjet’ plane over the pacific off southern California. At these speeds it will be possible to fly from London to Sydney in two hours.

CDG -JFK 50 mn ….. nice , I like that.
Do LOCo’s have any plan to get a couple of those …. 😀

This thing is flying at 95,000 feet, what’s the sonic boom signiture going to be like at that altitude? The air is pretty thin up there. Thinner the air the less effectively sound is transmitted through the air.

Hate to be the party-pooper but that was one of the reasons Concorde failed to make a bigger impact (well, that and huge increases in fuel costs). The only places it would be able to fly supersonic would be trans-oceanic – like Concorde – and subsonic over land; how much would you enjoy your journey if the airport approach took twice as long as the rest of the flight? Sort of sports car back to horse and cart, again.
The only future for the majority of journeys would be for the aircraft to go orbital and figure someway of slowing down the re-entry to subsonic so that the neighbours don’t complain…

So how much does it cost per trip?

Anyone been able to find a video of the ship traveling at Mach 7? It would be near impossible to watch it up close but perhaps there’s something showing it leaving a contrail across the sky.

I found this on NASA’s website

You can tell just how big the B-52 is, the actual X-43A(the small black bit) is only 12ft

and i thought concorde was fast

???
Them images are very good but are there any of the separation and any from when the rocket fires.

No, plenty of it in water, H2o and all that.

Is Hydrogen expensive?

If you burn Hydrogen the only waste product is water, though I do beleive oxygen is also released… not sure

So, London-Sydney in two hours… And how will the sonic boom be dealt with?
That was the death blow to much of the Concorde project…

Nice to see the B52b, the oldest one still flying, 008, with the very early engines still doing the launches. The black smoke on take-off was spectacular, and noise 😀 😀

ITV News excelled themselves by calling it a SCAM jet. I know the brief explanation was something to do with hot air but that’s ridiculous.

it landed in the pacific oceon it is on sky news that it says it broke the speed record hypersonic 5000mph and this wont effect anything they have scrapped this plan for a while as they are doing space exploration
