from the BBC site -----
"..Another person who reported hearing the boom, who gave his name as Dave, from Warwick, described the sound as "like sitting on a hard shoulder and a big lorry going past"....."
I think we should be worried ....

I really don't understand the big fuss? Go up to Cap West and all sorts go ss to show off to the spotters and jotters everyday. Or Wrath. Or Pembrey.
One sonic boom over middle England and everyone declares the end of the freaking world. We have had aircraft that can break the sound barrier for a few years now. Get over it.
Jesus, I used to sit and watch F4s on QRA do max rate climb outs from Wattisham, fully fuelled and live armed to stop Ruskie as part of my job supporting them. No one gave a flying toss when every single one of the 2460 panes of glass in the lettuce sheds in Wetheringsett blew out, again, for the second time this month.
Anyway, helicopter on the wrong frequency, for a QRA call? I smell the brown stuff that comes out of bulls. More like the giant radar sig over SW England that anyone with any understanding of radar could understand. A big f-off balloon, well, solar balloon. Not rare, not alien, not terrorist. Didn't cause any problems to anyone.
And Dave can go stick his head up a frigging pig!

LOL, I'm chilled, honest.
It's the bull spouted everyday by the Facewitter community that grips my s**t.
Airplanes go fast. Is not an earthquake, no need for a tsunami warning.

My folks live in Bude on the Cornish coast and back in the concorde days you always had people moaning about it going supersonic too close to the coastline due to the sonic boom and it gradually got moved further out to sea.
USAF also used GCHQ Bude (loads of radio masts and dishes) as a targeting site for training and you used to regularly see a pair of F15’s tanking it at low altitude over their house. Not supersonic but still loud enough to rattle the windows and your glassware / crockery in the kitchen cupboard. I guess if you don’t like jets it could get a tad annoying but I say rock on

A friend of a friend who's army based up there said just after the noise, fire engines with sirens on left the base.
Bit weird if they did. Must have been going somewhere unless it was an eloborate exercise for the emergency services to see how they handle a terrorist threat/explosion?
That's my new conspiracy theory btw lol

Taken from comments on a YouTube clip I was watching:
There is 3 transponder codes that you can transmit. I suspect the helicopter was 'squawking' 7500 which means the helicopter has been taken over ie by hostages or a rogue passenger. I was taught them as:
7500 - (75, taken alive)
7600 - (76, in a fix) to indicate a comms/nav failure
7700 - (77, going to heaven) mayday situation aircraft is in imminent grave danger. You can also transmit a voice distress on 121.5, this is the frequency that Breitling emergency watches transmit on,
Sounds like bingo

I'm curious in the amount of trouble the pilot is going to get into! Plus imagine seeing a typhoon coming at you at full speed.
Personally, I'm happy that it went SS, Imagine if it was a standard airliner doing a 9/11 style run?

I do smell a Rat here, run up to the Olympics and we have Typhoons blasting across the country on full reheat because someone did the wrong squawk in a little chopper.
Are we led to believe that every light aircraft, small helicopter, microlight or Gyrocopter and it's pilot has the ability through a slight slip of the finger on the radio gear to scramble 300 million pounds worth of Eurofighters from 200 odd miles away at supersonic speeds, surely there are other ways of dealing with this like ATC speaking to the pilot. There are thousands of aircraft movements every day and by the law of averages this would happen occasionally, perhaps when techs are testing or diagnosing equipment, when pilots are under instruction etc.
Also, the time was 18.10, kind of rush hour, looks to my cynical mind like it was contrived so it caused the least impact it could, I guess they practice this kind of stuff out to sea and whatever but this sounds like a dry run for intercepting something that threatens the Olympics, fair play if it is, I dont have a problem with it, in fact I am sorry I missed it, we pay for the bloody things I want to hear them Boom !

Just wish I’d seen / heard it. Seen a few clips but just the sound above as they circle the chopper and nothing visual.

I am no pilot either, just kind of seems overkill for a small chopper broadcasting a transponder code, I cant imagine that with all the aircraft, equipment and people involved that it doesn't happen more often, ok pilots are a lot more professional than the average but they still get stuff wrong, so if the heli pilot got it wrong this time I am sure it has happened before. It just doesn't add up, if nothing else it may have been accidental but the reaction seems to have perhaps been stepped up.

Perhaps for fifteen quid, buy this, hook it up, set it to 7500 and bingo ! your very own Supersonic airshow !!

Still, setting a 5 instead of a 0 is not as easy as doing 7700, don’t forget they go from 0-7, so 0 is next to 7 on the dial.

Depends if your within true radar range or not...
If your within a range of being (for lack of a better word) painted, then transponder off wont make you suddenly disappear. You'll be Transmitting no identifiers etc, however youll still be a blob on the screen.
If your out of active radar, then effectivly, yes.
Wiki explains it
