NASA X43A Scramjet

Your the dumb one, there are many different miles.

they don't plan on using it more than once, so why worry about long-term heat resistance?

100 kilometers = 62.14 miles dummy

Damn, i used to live where they tested these things in South Australia. I probably would seen them flying over if id have stayed...

it should have crashed landed on your house..

edz3511: yes you got me there i did quote from clarkson, but it's not the only place i checked, as I did research a bit after reading the whole thing from clarkson, although its much more easily said by clarkson. It's obvious people take info from somewhere and quote, but i did research in other places.. but what was my mistake was not explaining where i took it from

interesting comments, especially by felipehuerta346, remarkably, it is almost word for word the same as what jeremy clarkson wrote in his book, the world according to clarkson volume 2 and another thing....

its 62 not 60

new Scramjet is there in Oktober 2009
will be tested X-51 or like that
it should be 20.000 km/h fast :D
we could reach the Space
thats really cool

Too bad it goes so fast there's no video of it.
