Reminds of a story from 1895, at the time there were only two cars in the state of Ohio and they managed to crash into each other. Some people believe this is only a folk tale.
For those who don’t already know, a Mach number is (basically) how many times the speed of sound something is going. If you’ve ever been in/seen an airplane break the sound barrier, at that precise moment it’s at exactly Mach 1. With that in mind, Mach 50 is pretty ridiculous.
There seems to be a more powerful black hole in Washington D.C. Sucks in money, emits olfactory organic compost.

> This image from 1947 looks down the throat of what was then the world’s largest tunnel. The scene is the NACA’s 40 × 80 foot wind tunnel at Ames Aeronautical Laboratory. The camera is stationed in the tunnel’s largest section, 173 feet wide by 132 feet high. Here at top speed the air, driven by six 40 foot fans, is moving about 35 to 40 miles per hour. The rapid contraction of the throat (or nozzle) speeds up this air flow to more than 250 miles per hour in the oval test section, which is 80 feet wide and 40 feet high. The tunnel encloses 900 tons of air, 40 tons of which rush through the throat per second at maximum speed. Dwarfed by the immensity of the tunnel structure, the experimental model seen here is actually almost 50 feet long. Embodying a sharply swept-back wing suitable for supersonic flight, it is undergoing tests designed to improve the landing characteristics of this type of airfoil. Mounted on struts connected to scales under the test section, it is “flown standing still” while each element such as lift and drag is measured and air pressures occurring across the wing are recorded. Information gathered from such tests were made available to the nation’s aircraft manufacturers by the NACA (now NASA).

Wonder if that massive black hole is the center of a galaxy?

These facts are out of this world!

Why were Buzz Aldrin and Neil Armstrong on Luna 15? (Editing is more of an abandoned, rather than lost, art.)
Pedmar Premium Member over 1 year ago
Luna-15 was just the cover story. It was really an Illudium Q-36 Explosive Space Modulator.

Because, who doesn’t need Mach 50 winds every once in a while?

How big is the largest black hole ever detected?

Google sez the Luna 15 probe crash site was 530 miles away from where we landed.

Mach 50 still couldn’t blow the leaves from my yard.

They used that wind tunnel to test speakers.

Perhaps Buzz and Neil learned that was merely one more such moment of their history. Nothing new then either.

Best jetting speed? Foot by foot.

You can barely make out the writing on the side of that black hole: Universal Rundle

wind tunnel (was?) a few miles from here..

word comes from my better half (who once upon a time worked on base) that nasa eventually switched to computerized wind simulations instead

So those sneaky Russians were testing drone attacks even in the 60s? Despicable!

Of course they didn’t hear it. Sound travels by air.

And Luna 15 just missed them but “that” much.

The real question is, “If a Luna spacecraft crashes on the moon, does anyone hear it?”

In space, you can’t hear a space probe scream.

I’ve been to NASA Langley and been inside one of their wind tunnels but I think the one mentioned in RBION is else where.

so much for the USSR getting to the moon first before the USA, right?

Busy day at the Moon. Millions of years of nothing happening, then everything at once.
