Strange, very loud sounds in the sky

[Heel n Toe]

Have any of you guys heard any of these very loud strange sounds seemingly coming from the sky? We were in the dining room near a window about nightfall a couple of years ago and heard one. It grew in intensity, remained really loud for about 2-3 seconds, then trailed off. I went outside, but it had already stopped.

It made the local news and one of the reporters kept following up on it with Ft. Jackson and Shaw AFB, but never got an answer.



The one we heard sounded most like those heard in the segment that begins around 1:55 in this one... (excuse the photo shown before you click... nothing in the footage like that):

Here's one for you guys in the Flagler area.

We can only speculate. I would have to guess it is some secret military program. Hopefully it is our military testing a new high speed high altitude something. I would like to think we have something as advanced as the A-12 was for 26 April 1962. If they can build that with slide rules what can they build now with super computers?

Search Trumpets around the world, we had that same sound here. Kind of creepy.

Lockheed Martin’s Skunk Works has confirmed that it is developing the SR-72 spy plane. The successor to the SR-71 Blackbird, which was capable of Mach 3.5, the SR-72 will be a hypersonic unmanned aircraft capable of Mach 6, or just over 4,500 mph. At hypersonic speeds, the SR-72 will be able to traverse any continent in around an hour — meaning, if they’re strategically positioned around the world on aircraft carriers, the US military can strike or surveil any location on Earth in about an hour. It is also suspected that the SR-72′s hypersonic engine tech — some kind of hybrid scramjet — will find its way into the US military’s High Speed Strike Weapon (HSSW), a missile that can theoretically strike anywhere on Earth in just a few minutes.

The SR-72, despite the similar name, is a completely new plane. At the moment, the SR-72 is still only a concept, though Lockheed has now confirmed that the plane is in active development. An optionally piloted scale version of the plane with a single engine will be built in 2018, with test flights scheduled for 2023. If all goes to plan (funding hasn’t yet been secured by Lockheed Martin), a full-size SR-72 (about 100 feet long) will be built and tested by 2030. As it stands, the current plan is for the SR-72 to be unmanned. It will be a very, very large drone.

While the SR-72 will undoubtedly be a paragon of stealth and fashioned from monolithic crystals of titanium wrapped in carbon fiber, its defining feature is its operational speed of Mach 6 — or 4,567 mph (7,350 kph). At this speed, the SR-72 can cross the Atlantic (or Europe or China or…) in about an hour — or circumnavigate the planet in six hours. At an operational altitude of around 80,000 feet (24,300 meters) and Mach 6, the SR-72 will be almost impossible to shoot down.

To reach Mach 6, some aeronautic magic needs to occur, otherwise we would’ve built a Mach 6 aircraft years ago. Basically, turbofan engines — like you would find in every big airliner — are only really efficient up to around Mach 2.5. Ramjets can then take you to around Mach 4, but then they too lose their efficiency. To get to Mach 6, Lockheed’s Skunk Works lab — which has developed such luminaries as the U-2, SR-71, F-22, and F-35 — is working with Aerojet Rocketdyne to create a turbojet/scramjet hybrid engine that uses a turbine at low speeds, and a scramjet (supersonic combustion ramjet) at higher speeds. Like the SR-71, these engines will have the same inlet and nozzle, with some kind of mechanical system that shifts the airflow between the two portions of the engine as airspeed changes. Whereas a ramjet decelerates incoming air to subsonic speeds, a scramjet is supersonic throughout, allowing for much higher air speeds (no one knows quite how fast, but we’re talking about at least Mach 10).

Sounds like Hell opening up.

[HardDrive]

Sounds like high altitude aircraft to me.

The earth is going thru a thick part of the asteroid belt right now. Go outside on a clear night. You can see up to 20 meteoroid streaks per hour right now.

I thought they NEVER confirmed what they were going to do, and only confirmed what they had done hesitently, and decades after the fact.
I'll bet my last dollar that an SR-71 replacement (maybe unmanned) is already flying, but I'll bet my last 2c we won't see it for another 20 years.

(Why am I so sure? Because the USAF rolled over on the SR-71 program being cancelled. They'd have never given in that quietly unless they had something even better in the shed)

That's just Jupiter.

In both cases, even though the causes of acoustic-gravity waves are of a quite understandable geophysical nature, they are indicative of the expected significant increase in solar activity and the geodynamic activity of our planet. There is no doubt that processes in the core rule the internal energy of our planet, therefore, we should expect by the end of 2012 a sharp rise in strong earthquakes, volcanic eruptions, tsunamis and extreme weather events with peak levels in 2013 - 2014.

Seems like this prediction has come true...

Riders on the storm
Riders on the storm
Into this house we're born
Into this world we're thrown

Like a dog without a bone
An actor out alone
Riders on the storm
There's a killer on the road

His brain is squirmin' like a toad
Take a long holiday
Let your children play
If ya give this man a ride

Sweet memory will die
Killer on the road, yeah
Girl ya gotta love your man
Girl ya gotta love your man

Take him by the hand
Make him understand
The world on you depends
Our life will never end

Gotta love your man, yeah
Wow!
Riders on the storm
Riders on the storm

Into this house we're born
Into this world we're thrown
Like a dog without a bone
An actor out alone

Riders on the storm






I really don't know why, it just seemed like the thing to do.
