Never heard of GlobalChickhen. Care to expand on it?
I am guessing it isn't KFC.
But to answer the original question.
I honestly don't know if there is an Aurora / SR-72 Plane.
But I have every confidence that America is working on multiple supersonic prototype planes, when or if we'll every officially know of them, who knows...
Saying that there is ample evidence, that objects are traveling at supersonic speeds, across america and other parts of the world.
There is a military need for such planes, given america's agenda to push it's brand of liberty and freedom across the world.
And there is the technical and theoretical methods to achieve such speeds.
So time will tell on that front.
The one project I am most intrigued be is Skylon.
A join project with America and the UK, to build a SSTO (Single Stage To Orbit) Plane.
Capable of taking off and flying like a conventional plane at about Mach 5-7 using air. Then switching to a compressed air and hydrogen mixture to achieve low earth orbit.
Potentially a similar usage and capacity as the Space shuttle, but significantly cheaper per flight.
