“When the nuclear bomb was detonated at the bottom of the shaft, the nuclear material released 99.9% of its total energy within a millionth of a second.”
Serious question for the casual reader- when you read a sentence like that, does it not harken back to the kinds of things you’d hear 9 year-olds say on the playground?
99.9% and a millionth of a second.
Seems oddly non-scientific and more- something else.
Agree …
Fastest pitch ever
The fastest speed ever?
— The speed at which GCP responds to anything to do with the Rapture.
— The speed at which Mygirl’s head explodes when she sees a picture of Trump in diapers
— The speed at which Arch (and about a dozen other TPBers) gets a boner when something nice is said about Israel
All three of these speeds have exceeded the speed of light.
This a tribute to the Federal Govt. and its minions that the greatest speed achieved and “sent into ‘space’ ” would be a metal plate typically thought of as a COVER over an access to a labyrinth of subterranean tunnels that deal with the transference of human waste and feces.
Perhaps there should be a “journalist’s” award for the “Golden Manhole Cover”, an award for blowing a cover-up.
Naw…
Just like the manhole cover, they’d never be seen again.
Which item would be more intriguing to “the aliens”, the Carl Sagan disc, or a glowing manhole cover?
Besides all of that… the images of earth are spherical and they mention gravity?
wtf?
The article wasn’t meant to be read by those with a sense of discernment, for example-
“…the SR-71 broke the world aircraft speed record when she reached over Mach 3.3 or 3,529kph(2,193 miles per hour) on July 28th 1976.
Amazingly, the Blackbird does not have a top speed. Her engines and airframe could reach much greater speeds, except she is limited by one thing…temperature. If the SR was allowed to fly as fast as she could, she would continue her acceleration until literally beginning to melt from atmospheric friction. ”
Followed by the following-
“The X-15’s official world record for the highest speed ever recorded by a manned, powered aircraft, was set on October 1967, when William J. Knight flew at Mach 6.70, at a speed of 4,520 miles per hour.”
And yet it didn’t melt from the friction. Perhaps they should have built the SR-71 out of the same material as the X-15. Or better yet the same material as the manhole cover that is still flying through space at a 150,000 mph- allegedly. The dichotomy is not explained. And both are manned aircraft and both are claimed to be the record for aircraft speed although the speeds are different. So which one is the record holder? No explanation is provided to account for the discrepancy in records.
Should build it out of Saudi Arabian passports.
Great comment, made me laugh.
x15 altitude for speed run 19.1 MILES for a ROCKET PROPELLED VEHICLE
sr71 altitude for speed run 16 miles for an AIR BREATHING VEHICLE
x15 is a dart with stubbys and need a mothership to get up to 35k
sr71 can take off from a LOOOOONG runway.
Also the x15 has hit ” space ” at 50 miles up a few time iirc
The fastest man made was the ejecta from any nuke
Again, terribly written and incorrect, but not proof that the X-15 never existed.
The notion that a jet engine has unlimited speed is nonsense. However, the efficiency of jet engines in determined by (remarkably) a single factor: the temperature of the combustion chamber. The materials that turbines are made of are called Superalloys and melt at ridiculously high temperatures.
Now, I am highly skeptical that the SR-71 would “melt” if it went as fast as it could, I can easily explain why an X-15 would be able to fly much faster than an SR-71 and it has to do with the Bernoulli Equations. These equations allow aircraft to fly…which obviously you believe that they can or else how would they spray chemtrails everywhere? (sorry, I couldn’t resist).
The Bernoulli equations describe the RATIO of lift to drag of an airfoil moving in air. (In fact, everything has these characteristics, but it only really useful when applied to airfoils.) Different airfoils have different lift/drag ratios. A simple way to look at it is: Lift is what allows flight to occur, drag is the price that is paid. This is independent (more or less) of material. Anyway, the drag of the X-15 is simply lower than that of the SR-71 at high speeds, therefore the friction is less at high speeds. So, why not simply make the drag ultra-low on all aircraft? Simple…takeoff. In order to take off, a plane needs sufficient lift at takeoff speeds. Therefore they need a higher lift/drag ratio at low speed which is going to make more drag at higher speeds.
So, how, one might ask did the X-15 ever take off? It didn’t. It was lifted off the ground under an B-52, released with sufficient speed and altitude to ignite its engines and reach its full speed.
Good onya … it was for fun. Lots of technical discrepancies.
Man hole cover lives matter.
The fastest speed ever achieved is the speed a woman can jump to conclusions .
Sorry ladies .
haha have heard about that! Shame there were no rapatronic cameras filming it. I doubt it would have left the atmosphere as the drag would have been massive despite its initial velocity
