The first article also mentions the plane reaching 7 mach. But they first say that the pegasus missle it was launched with, reached 5 mach and the plane it selff 7 times the speed of sound.
Size doesn't matter.

If it's an engine that uses air as fuel the how the hell is it going to work in space?
Unless they're just going to use it to get out of the atmosphere, then it makes sense.

You'd be surprised how little you need to propel yourself through space.
Lots of spacecrafts release xeon gas to propel themselves. Thats about as powerful as a sheet of paper pushing down on your hand.

lol
Most rollercoasters only go at about 40-70 MPH. I wonder what Mach 5 will feel like.

Mach 5 is old news...they did that way back when they were using the X-15 rocket plane. Which, by the way, also managed to reach altitudes that qualified its pilots for astronaut wings. It was launched from a B-52 and landed like a conventional plane. I forget what the speed record was for that thing, but I don't think it's been reached or broken until now.
Oh, 'scuse me, that's for powered flight...the shuttle goes much, much faster on re-entry.

If the scramjet needs the air moving at mach whatever to prime this engine, then why not just have an engine primer capable of ramming air at mach whatever while the thing takes off conventially? Then once the intermix pressure reaches the design parameter, let the primary engine fire, and take over.
Wonder what thier thoughts would be on that? That way we wouldn't need a 747 to get the thing launched.
