discussion Bangs In The Night!

[ojays]

Did any of you here the bangs/explosions last night.

Could it be related to this!

This also makes interesting reading.

This one of those chem trail conspiracy things isn't it!

Just keep an eye for this chap View attachment 93487

just careful he don't get his discombobulator out

They denied the Stealth program, they have to, if this is a new technology then they will also keep it quiet. Thing is not much use when you can hear thing from the other side of the world banging and crashing

[ojays]

No they are speculating it is to do with 'Pulse Jet Technology' and the so called Aurora Project that has been talked about forever!

How can you have stealthy aircraft that announces it's departure so un stealthily.

As far as I know and I might be wrong but as soon as an aircraft goes faster than the speed of sound it creates a concussion sound wave that sounds like a bang so I think might be the bangs people have heard

Looks to me very much like the after effect of an Elephant's fart

A supersonic shock wave bang is a single sharp event. Last year there were constant reports of low rumbling noises heard across parts of NZ, mostly in the cities of Auckland and Wellington. The answer was never found. And it stopped.

We may have exported our Kiwi Stealth bomber squadrons to the UK for evaluation.

Joe I have never never ever known a Kiwi to do anything in stealth way.

In my retirement occupation, filming weddings, there were a load of Kiwi "All Black "types some playing for Jersey (UK) friends of the groom. During the interval they came on to the floor and I had the real pleasure of filming the "Hacker". I had 3 cameras going and I had a ball editing the Hacker sequence.

Matter of interest the Paris to USA Concorde passed virtually over the Island of Jersey. On the way out to the USA it gathered speed and went thro. the barrier. You could tell if it was early or late by each bang. A few of the greenhouses in Guernsey suffered broken panes. My heart bled for them . Strange thing was sometimes there were two bang. Came to the conclusion it changed direction and gave out two.

Sorry you had to endure that Laurie

These guys got into trouble for 'inadvertently' going supersonic and smashing the glass panes of the Federal Supereme Court in Brazil:

Not bad at all just gave a reminder. Guernsey though was nearer the flight path. The worst were the French Airforce Pilots. Left France and then thought we will show those Channel Islanders after stealing the Islands from France. And so they gave us a few thumps.

We have series of rocks between Jersey and France (Jersey owned oh YES) the Echreous. These mostly cover at hight tide but leaving some bits "a float". These have a few Jersey people with holiday homes on the top. Some ten years ago a French contingent decided to invade and take the Islands. So we sent a couple of Jersey Bobbies out there on this lovely sunny day. The story is they came to an amicable solution over a few bottles of red wine. Would you believe that.

That seems a logical conclusion

I'm sure a few will have seen this but thought I would share as I find it funny on the subject of stealth

From R Brown (19 Apr 2011):

A few years ago at our Air Traffic Centre we received warning that an undisclosed number of US Air Force B2 Bombers would be crossing our FIR [Flight Information Region] at a particular time on a particular day. They would check in with us as they entered our airspace and check out again as they left. They gave us the callsign to expect, and the route was known, so it was logical to assume that they would contact us at a certain time at a certain place. The callsign and reporting points have been changed to protect the innocent. Being the then famous new 'Stealth' bombers we would know little about it but they would pay us the courtesy of letting us know they were there. Eric, a very capable controller with a keen sense of humour was on position, and heard,

"UAE Area, this is USAFB2. This is a courtesy call advising that we are about to enter your airspace."

Eric replied, "USAFB2, welcome to UAE Airspace, we have you on radar 200 miles out over LOTUS, hope you enjoy your visit."

Without thinking the Stealth Bomber replied, "Thank you UAE, it a pleasure to be... Wait - you got us on Radar? 200 miles out? You shittin' me?"

"That's affirmative USAFB2," said Eric, "I'm shittin' you. Enjoy your visit."

That's got to be an April fool ! That pilots a new guy and there convinced him there's an invisible plane there and he's going to fly it !

The next picture is of him lying on his back in agony while everyone else is laughing like mad men

We thought over the last couple of weeks we were woken by just that but the mystery was solved last night by my missus apparently I fart in my sleep.

 

[stona]

A supersonic shock wave bang is a single sharp event.

It is for one observer in one position but it is a continuous event, as long as the aircraft remains at supersonic speed. Two observers a distance apart but both on the so called 'boom carpet' will hear a sonic boom at slightly different times, depending how far apart they are and how fast the aircraft is travelling.

Not all booms are equal being a function of the physical properties of the aircraft producing the effect as well as its altitude etc.

Cheers

I've always heard them as a double bang ie b-bang, as there is a shockwave from the nose and also at the tail. It's known as a N wave, one boom is caused by the nose as the pressure rises and the other at the tail when the pressure drops back to normal.

 

[stona]

The two shockwaves merge into one supersonic wave travelling behind the aircraft (space ship or flying saucer for those of an imaginative disposition) according to my old physics teacher. Mr Snell (he must have been good because I can remember his name 45 years later) was quite keen on practical examples to interest young boys, luckily for me. This would have been around the time Concorde first flew.

The double boom is caused by another effect. A boom accompanies any rapid change in pressure, hence an observer hears one as the high pressure wave arrives and another as pressure returns to normal.

I mentioned we some times used to in Jersey received two bangs apart, Could be quite a time.from the Concorde. Can any one say if that is due to direction change (of the aircraft that is not the Island ).
