Just press F12 on a language Lab computer.

Thank you. Do they test high velocity air-breathing engines like that, or using a more trial by fire method?

Can a wind tunnel get up to scramjet speeds; ie. Mach 6-12?

Thanks. Thing is that at Mach 25, surely even though it is very thin, you are taking in some? Do you know if such a scramjet would work, even if it had very low thrust? And for the sake of the theory, assume that there is no drag.

I was doing some Wikipedia browsing, and I came across the concept of Scramjets for spaceplanes. The highest estimate for a top speed of a scramjet in atmosphere is Mach 25, which is approximately orbital velocity. The ionosphere contains high levels of O, so would it be possible to fly a...
