Saw this article on Drudge earlier today. Make of it what you will. The more MSM hits the idea, the more quickly it could be coming to the open!



It makes the same kind of pulsing sound as the one on this audio,' he told MailOnline after listening to a recording of the bangs that was taken in south London on Saturday night. ‘When we run a test engine it’s a real industrial noise and you can hear it for miles. We have people coming to us asking to make less noise or keep it to the daytime.'

While the MoD said it had no reports of aircraft in British airspace capable of making a supersonic or hypersonic boom - or any alternative explanation - one expert claimed the noises could have come from thousands of miles away. That could explain how the same sounds were apparently heard on both sides of the Atlantic at the same time. Steven Aftergood, a government secrecy expert at the Federation of American Scientists, said: 'If an aircraft is responsible, then it’s worth noting that it may not be local at all. 'Because the sound wave that causes the boom can be reflected by the stratosphere, the source of the event could conceivably be hundreds or thousands of miles away from the place where it is heard on the ground.' The video of the PDE was filmed in 2008 at UT Arlington Aerodynamics Research Center. It shows two ground tests of a hydrogen and air pulsed detonation engine. It is slightly faster than the sounds recorded over the UK, but the repetitive nature is the same. A PDE works by sending liquid methane or liquid hydrogen through the engine. The fuel mist is then ignited. This detonation is made inside a specially designed chamber and occurs when the aircraft is travelling beyond the speed of sound. At these speeds, a 'thrust wall' is created. This is when the craft is travelling so fast, air is pushed near the aircraft's nose that creates a 'wall'. When the detonation occurs, the aircraft's thrust wall is pushed forward, and this is repeated numerous times to propel the aircraft. As a result, the contrails created by such engines appear to look like rings on a rope, or even a spine. It can theoretically power planes at five times the speed of sound. The technology builds upon 'pulsejet' principles which first emerged in the early 1900s and were used in German V-1 flying bombs. Test flights using the most recent forms of the technology have lasted only a few seconds, but it is still listed by conspiracy theorists as a potential source of power for the so-called Aurora spy jet Read more: www.dailymail.co.uk... on-reveals-sounds-identical-unexplained-noises.html#ixzz3KgGlvvWh Follow us: @MailOnline on Twitter | DailyMail on Facebook

Too bad they suck as aircraft engines.

I've never once heard of a sonic boom of any kind, even the shuttle, being heard more than a few hundred miles at most. I don't know where they get "thousands of miles" from.

I'm pretty suspicious about all this.

There was a huge fireworks display in South London at 9pm when a lot of the tweets were posted. I heard it, thought it sounded strange and headed to my roof and I could see and hear them and I live 14 miles away. The big ones were still really loud. I think that probably accounts for a lot of the reports.

Obviously doesn't explain reports from across the country (or even across the Atlantic).

It is interesting that their "expert" that states sound can be heard over thousands of miles is by trade an electrical engineer. I wasn't aware that being an electrical engineer made someone an expert on sound wave propagation through the atmosphere.
He seams to be deep into U.S. governmental conspiracy theories as well.

If heard on both sides of the Atlantic... could it simply be a meteor of large size blasting through the atmosphere?

Coincidentally timed with the fireworks display?

Look at the timing. First report from the UK was 1900. Reports from New York at 1530-1600ish. There's a five hour difference from the UK to New York. That means it was heard at least an hour and a half later in the US.

Hmmm..
Well.
Well that blows my theory..
Thanks for pointing that out...

So goes back to possible air frame..
Would say new SR-72 .. but we know from the SR-71.
That it doesn't take 5 hours to travel across the Atlantic...

I'm stumped .....

No, the TIME DIFFERENCE is 5 hours. It was about 90 minutes between the first boom in the UK and the ones over the NY area.

At 7pm in the UK it was 2pm in NY. But the booms over NY weren't heard until around 330pm.

I'm trying to follow here
so my ideas stink on ice. So I will toss that out the window.
The recordings sound like fireworks ...
But if heard in Buffalo NY ..
The speed of sound is 767 MPH..
So if a meteor were to enter..
It is possible for to sound to travel air even bounce off the inner atmosphere.. and end in Buffalo NY. Again the idea is out.. timings are off..
Soooooooooo.....

I'm suspicious that you may know something more.. you said they make bad engines.. but the UK has had time to refine on black projects..
And so has the USA...

What do you have in mind?

Just throwing in some rough calculation: The distance from the middle of UK to the middle of NY is aprox. 3400 miles. If an aircraft made that distance in roughly 90 minutes it would have to travel at 2266 mph , or around mach 3. A reasonable cruising speed for an advanced ISR platform possible using a new fuel that looks green under full power sprint on a return trip to the states.

That's just speculation though.

I guess the SR72 drone isn't completed yet but :

complex.foreignpolicy.com...

AND it is called Aurora,THAT would tie up conspiracies a bit...

Oh boy... the green dragon?
Thanks for calculating.


I'm having a rough time and can't make sense of it. ( in between surgeries)
My meteor theory is out.. because like the one in Russia.. it had speeds in the 10's of thousand miles an our..
Plus strong damage from shock waves at very high altitudes... so that's out..

Hope someone gets a pic...
Sadly the aircraft will be miles beyond the super/Hypersonic booms..

If the audio is a PDE, then the fuel flow rate is way too high. Sounds a lot more like fireworks or small arms fire to me.

Sound ducting can occur, but I'm not sure "thousands of miles" is plausible. On one, hand you could say millions of miles, because if the wave (sound) has enough energy(X), it could go (Y) miles. Seems like a fluff piece.

But the top two articles at the link under "most read" at the moment are both "Aurora" articles, so you can bet you'll see more of them. Hopefully they'll have something more interesting than this.

Cav,

I'd discount that article you posted. They have figured out a lot since the SR71.

I might tear my hair out if someone on the MSM references the "Aurora" one more time..
