A team that includes NASA and the U.S. Air Force Research Laboratory (AFRL) is celebrating the successful launch of an experimental hypersonic
scramjet research flight from the Pacific Missile Range Facility on the island of Kauai, Hawaii.
NASA, AFRL and Australia's Defence Science and Technology Organisation (DSTO) are working with a number of partners on the HIFiRE (Hypersonic
International Flight Research Experimentation Program) program to advance hypersonic flight -- normally defined as beginning at Mach 5 -- five times
the speed of sound. The research program is aimed at exploring the fundamental technologies needed to achieve practical hypersonic flight. Being able
to fly at hypersonic speeds could revolutionize high speed, long distance flight and provide more cost-effective access to space.

I admit,I do not follow air craft technology as closely as I probably should,none the less,I figured there are those on here who do follow the latest
updates/advancements in Aeronautics that would be interested in this article.
It is amazing how far we have come in only the last 50 years,not to mention overall since the wright brothers first flew.
The conspiracy theorist in me says 'if this is what they are willing to show us
,imagine what they have behind closed doors,away from the
public and prying eyes'
In summary -

"This is the first time we have flight tested a hydrocarbon-fueled scramjet accelerating from Mach 6 to Mach 8," said NASA
Hypersonics Project Scientist Ken Rock, based at NASA'S Langley Research Center in Hampton, Va. "At Mach 6 the inlet compression and combustion
process was designed to reduce the flow to below Mach 1 -- subsonic combustion. But at Mach 8 flight the flow remained greater than Mach 1 or
supersonic throughout the engine. So this test will give us unique scientific data about scramjets transitioning from subsonic to supersonic
combustion -- something we can't simulate in wind tunnels."
'The HIFiRE team has already achieved demonstrating supersonic combustion in flight with a hydrocarbon fueled scramjet, in comparison to a
hydrogen-fueled scramjet. While hydrogen fuel is more reactive, hydrocarbon fuel offers many benefits, including operational simplicity and higher
fuel density so a hypersonic vehicle can carry more fuel.'
I leave it to the experts and enthusiasts,Enjoy!
