Ran across this image today...Mt Shasta during fire season 2018.

Not sure if this was already posted but it's really a good video (IMO)...gave me goose bumps.

"The partnership will allow for the development of a hypersonic aircraft for the presidential fleet, that can travel as fast as Mach 5. Hermeus successfully tested a Mach 5 engine prototype earlier this year. A demonstrator vehicle using the Mach 5 engines could be seen within the next five years."

Looks like the load shifted and they had to bring in a crane. Someone was either driving to fast and hit a bump in the road or tie-down chains broke? Or both?

No drama or mishap. Just a new resident moving to the Hill Aerospace Museum at Hill AFB in Utah.

Space X does it again & I love HP

I believe around 27,000 GpM is the rating for the fuel pump &
500,000 HP

BTW, a turbo car on the street @ 1.5 Bar had me peeing my pants

Thanks Kevin993,
In the 4th picture down, it looked to be hanging off the rear of the trailer. Could not see jack stands but did see the crane hook and strap holding up the nose. So it kinda looked like the load shifted on the trailer. But instead, the crane was holding up the nose and the jack stands were there while they drove the trailer out from under the aircraft.

seems surprising that those angles which make it so radar invisible, and all the design/aero work would not be kept reasonably confidential.... just giving away this technology that years and billions were spent on perfecting. jmho.

[abisel]

Not only the angles to deflect/reflect radar signal away from the source, but also the engine inlet screens (not shown) and exhaust ducts. And the paint/coatings. Lots go into the stealth. Old news nowadays.

Not to mention that it can't fly aerodynamically. It needs computers to do the job.

I remember the first time I saw a couple F-117s in flight, I was driving by Holloman AFB. Looked like black diamonds on takeoff - so weird. I imagined it must have been the same in the late '40s when people saw airplanes without propellers for the first time.

I later got to take a peek inside the cockpit of one and it was quite ordinary.

I have no issues with drones of this configuration for remote/autonomous work without a pilot on board. Helicopters have some ability to recover from power loss (autorotation), but what do you do with one of these piloted drone-like things in the case of total power loss? It seems to me to be a very bad idea to put a pilot in something that has no hope of flight recovery if something goes wrong...

Very cool.

To attempt to answer your question, whole craft parachute like the Cirrus?

Maybe inflatable impact bags like a Mars probe?

Wingsuit?

Depends which one you saw..
The original test planes had no full cockpit avionics, no glass.
Looked very dated.



When they flew it to the museum, it was first mediablasted since the coating was secret , a very toxic process for those doing the work.. hence toxic death rattle can in flight to the museum where it was to be repainted..




And that one was the first to go to museum.. the others had a different cockpit with MFD's





Everything was taken from F16 or F15 inventory and being a black project, booked as regular F16/F15 spare parts

I'm calling BS on that.

Laminar wings aren't a new invention.. P51 mustang had wings like that.
Didn't go to 60k feet tho.. despite 3 times more horsepower and an 11 feet prop


I would expect this thing to have vicious stall characteristics without air going over it's horizontal stabs
