A thrill and a shudder.I don't know if this is accurate, but it is where the aero industry is heading.
China's New 12,000mph Engine Could Slash 20-Hour Flights To 50 Minutes
Recent advancements in aircraft engine technology have been more than impressive, especially with innovations like the Supersonic Hydrogen Jet That Couldwww.dmarge.com
The bottom line is, how much fuel does it need to make that 50 minute flight at hypersonic speeds?I don't know if this is accurate, but it is where the aero industry is heading.

I think for these flights altitudes, you do it more like a ballistic missile than an actual flying plane, do not need liftThe bottom line is, how much fuel does it need to make that 50 minute flight at hypersonic speeds?
At the rarified atmospherrc heights are they relying on mainly thrust to keep them at height?
The lift they would get from the airflow would be miniscule.
At those heights you start to get into the graveyard area where stall speed approaches cruise speed.
Ok for military use where a pilot and co pilot can eject.
Not much use for carrying passengers.

the problem is, you need slow flight to takeoff and climb to intermediate levels.I think for these flights altitudes, you do it more like a ballistic missile than an actual flying plane, do not need lift
True unless you have more like a rocket start, or variable wings, scram jets, etc the work for the engineers.the problem is, you need slow flight to takeoff and climb to intermediate levels.
Ballistic speeds and the acceleration create G forces that would kill us mere mortals.

They are looking in all the wrong places.The so far fruitless search for dark matter.
What a bunch of WIMPS.
The world's most sensitive detector has found no sign of dark matter. So where is it?
Scientists have yet to find evidence of WIMPs — one of the main contenders for dark matter — in the most sensitive test yet made. We explain what the new results mean.www.abc.net.au
Actually, it once again highlights that "The Science" is never ever settled.The so far fruitless search for dark matter.

Dark matter and dark energy, not observable.Actually, it once again highlights that "The Science" is never ever settled.
Dark matter was invented as a way of providing something that would tie in all the loose ends that cannot be explained via Einsteins theory of Relativity or the Standard Model of particle Physics.
It is equally possible that the concept of dark matter is a fools dream, just like the 19th century theory of a Luminiferous Aether that would explain the motions of the motions of the planets among oyher things.
Sir Isaac Newtons , brilliant thinker and scientist that he was, was a strong supporter of the theory of the Aether.
James Maxwell was also a big fan of the Aether theory to help overcpme some observable data anamolies.
It was Einsteins Theory of Relativity that effectively killed off the Luminiferous Aaether theory.
Perhaps its time to quietly send dark matter to the same round bin.
There are plenty of scientists who are looking for something other than dark matter to explain those pesky data points that point to failures in the theory.
