Known as hypersonic flight, it requires take-off and landing with a traditional engine.
However, it also requires a specially modified engine, that only ignites after it is already in flight.

Prototypes are soon to come from an Atlanta based company, that has financing from the US government and orders from around the globe. It plans to have a running prototype aircraft by 2023,
a cargo carrying model by 2025 and a passenger model by 2029.

It would allow travel from New York to London in an hour.
It might even allow long distance relationships doable...... at least for the rich.
The plane will carry less than 20 passengers. So, you know those tickets won't be cheap.
Still though, like flights to space, it may foretell what may be common day experiences in the future.

On October 4th, 1957 Russia launched a satellite into Earth's orbit. Named Sputnik, this satellite transmitted beeping radio signals that could be detected on 2 bands of amateur radio equipment 20.005 and 40.002 megahertz frequencies as it traveled around the planet approximately 18,000 miles per hour. Sputnik was a metal ball 23 inches in diameter with antennas sticking out that completed 1440 orbits around the earth. Each orbit was just over 96 minutes.

The batteries lasted for 21 days and Sputnik continued it's decaying orbit around earth until it reentered the atmosphere and burned up on January 4th 1958.

The photo below is a replica of Sputnik that is on display at the National Museum of the United States Air Force, Missile & Space Gallery in Dayton, Ohio.

Sputnik kicked off space exploration that started a rivalry between Russia (the former Soviet Union) and the United States.



Sputnik is the Russian word for satellite.

There was a wicked intense wind storm cross over my province a few days ago. Apparently, this happened.

Oh, ye light in the loafers Peebles! From those of us who used actually to get paid to ponder such juicy topics, I aver without a trace of malice. Not a solicitor (yet?), so I'll skip the discovery gleaned info, which is everywhere to see, ---and jump right into an anecdotal rant. So, this disgusting pile of piss poor black homosexual protoplasm allegedly tried his racist scam because he wasn't WHAT?!?! Happy with his "thesbian's" income. Puleeze! Look it up, and wonder which of us wouldn't swap paychecks with this cad. And allegedly paying only a little over $3 large for a couple of brothers to join in the fun. So he's also a tight wad. (Ask any wait person for the lore on tipping by race.) But I digress. This sculduggery is certainly greedy poor judgment on steroids. But what else, my people watching friends? Place his criminal antisocial escapade in context of how the alt left media typically jump with treetop automatic support onto such stories. Then consider how the same pundits fail to correct and appologize for such fake news "reportage". And finally, look at how many of these cases have been put upon us all over the years, beginning long before that despicable Towana Brawly's own little version of "Let's accuse, then sue, Whitey, and have 'Reverend' Al help us to get dem big bucks and a big book contract". Lot's more, chumps. But does the highly regrettable slave heritage explain it all in mere cultural terms, or has genomics had generational time to enter into the HARDwired fray? Industrial melanism, this time sans tree moths. Yet, what do I know?

I came to this seminar in good time to get a place on the first row, center.

…I always prefer to sit on the best seat be it opera, ballet, Yeti watching or just a domestic dispute…

I made myself comfortable for the next 60 minutes and immediately let deep and sound sleep consume my whole person.

… I never snore – checked against different sources…

So far so good. And my life was indeed heavenly sweet for the first half.

…Säg den lycka som varar…

Then, as usual, some forgetful bum’s phone went all excited somewhere in the bum’s bag’s intestines, which made the lecturer halt his stream of monotonic mumble, which consequently woke me up. My hardened nervous system wouldn’t have any difficulties to swing me back to sleep, but another bum – a very observant one – suddenly asked: “What’s that grey area under the curve?”. And that question put me on the perch straight and alert.

While the lecturer was staring at his graph as if he saw it for the very first time and the merry audience was suggesting solutions borrowed in the number of difference sciences – from landscaping to astrophysics, those oblique rotations in 3D – I recollected

…as a few years ago we used that very screen as a table cloth at a minor celebration when someone in our group published their first article and some clumsy bum spilled a bowl with dressing or the like…

and understood that the mystical “area under the curve” was just an oily spot, that looked grey contraluz.

Ages have passed, but I still consider my greatest contribution to the science that I kept composure until the end of the seminar. Then I went out, hugged a tree and laughed my heart out.

as I lovingly admire the reflection in my mirror.... But seriously, folks, here in the US northeast, so close ooooouuuuut there to OH Canada, EH?...even our evergreens shed a bit in the Autumn wind and storms. But it's the fall of the leaves, after the brilliant shows of color change, that hint, once agoin, how perfectly timed these changes seem. All entirely so that I can rake in more comfortable weather. However, our ecologist friends remind us that, what we see as beauty, beautifully choreographed hand in glove interrelatedness between, say weather and the well timed fall of leaves, has a brutal story as well. Countless generations of apparent mismatches, in these regards, with the demise of individuals, that finally yield so many links, on a species level. And, finally is the wrong word, as it continues. Sure, some groups can have enormously long runs, as with the angiosperms, many insects, and the dinosaurs. But in time, the ecological grim reaper calls us all. Mammals, also here for eons, take note.

----...the powerful glorious Sun.... Sadly, my formidable formal full scientific training doesn't include astrophysics, much less heliography, but I do know which end of my telescope to look into. And how to monitor sunspots, an important feature of amateur radio communications, and much, much more. The latter vary in their frequency of cycles and density, over the decades. But every century or so, these features of solar magnetic storms, and probably much more, get much more misbehaved. Sometimes they seem to correlate with periods of climate changes. As recently? Now, who knows how important are the roles all this, including mass coronal ejections, play in recent alleged or real climate changes? But it is striking how little we hear about the Sun's role in it all. The few real solar studies scientists have little to say, and when so, it's often muted and in lockstep. "No, no, it's all man made carbon/methane emissions." And by implication, the evil corporate capitalists. Hey there, Crazy Bernie. So I'm humbly thinking, why not more attention is being paid to the possible effects of such an all powerful good neighbor. Sure, some of the greenhouse gas theories make sense to me, but seems like there just might also be an elephant in the living room as well. But what do I know?

We are too tiny in this very big universe!

... experiences you have throughout your live, leave chemical markers on your DNA, essentially ingraining superficial experiences into your DNA.

I wonder if this explains "past life" memories that some people have?
