re: X-43a reached Mach 7 not Mach 10
Yea! Posting a Mach-10 figure was a mistake on my part.
Larry has corrected me.
But I do confess: Mach-7 by ANY "air-breathing" aircraft is nothing to sneeze at.
Congrats to the NASA engineers involved.
And if there WAS an Aurora, and it has been mothballed, it was most likely
NOT propelled by scramjet-engines [I've heard that it was powered by pulse-thrust].
So much the better the achievement of the X-43a NASA engineers.
May they go from Mach-7 to Mach-10 before the end of the year.
