I'm just going by Coventry local radio. Apparently they were scrambled (QRA??) because a helicopter pressed an emergency button. I have no idea what that means. It all seems a bit odd to me.

MOD just confirmed it was sonic boom caused by two RAF Typhoons.

I certainly wouldn't believe that, I attend airshows al the time and live near air bases, I know the sound of sonic booms and they wouldn't be heard in Coventry, Somerset, Oxfordshire and Warwickshire at the same time....these planes are around often enough to know the sound and we would all be used to it....

Olympic practise anyone ???

Simulated hijack, attack on air transport going to the Games ??

We will probably never know......

Just for Info...where are Typhoons based these days ??

PDUK

Does anyone have a video or sound recording of the sound? With so many people reporting it hopefully something will come out. These "sounds" are becoming pretty common around the world. The fact this is happening on every continent and none of our governments are saying anything has me really concerned. They must know something is up or even worse have no idea what it is. One thing for sure is it is REAL and it is HAPPENING world wide!!!!!

considering it was heard in cov & bath at the same time I find it hard to belive it was a sonic boom

Here's some info...interesting ......

Sonic Booms.....

Perception and noise

The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. However, as those who have witnessed landings of space shuttles have heard, when the aircraft is nearby the sonic boom is a sharper "bang" or "crack". The sound is much like the "aerial bombs" used at firework displays. It is a common misconception that only "one" boom is generated during the subsonic to supersonic transition, rather, the boom is continuous along the boom carpet for the entire supersonic flight. As a former Concorde pilot puts it, "You don't actually hear anything on board. All we see is the pressure wave moving down the aeroplane - it gives an indication on the instruments. And that's what we see around Mach 1. But we don't hear the sonic boom or anything like that. That's rather like the wake of ship - it's behind us.".[4]

Lincolnshire, and are recently being ''canibalised' for parts to enable an active fleet....so possibly thin on the ground.

I am used to hearing sonic booms but this didn't feel like it, I am pretty sensitive and would recognise it. The floor walls sort of shook.

Hey all, I heard military jets go over my house not sure what time it was though, maybe around 5pm BST.
I live in east yorkshire if that helps.

Edit [ Didn't sound like they where hitting the sound barrier,when they went over. Also im on the opposite side of the Humber Estuary to Lincolnshire where theres a base i think.]

I live just outside Coventry and didn't hear this :-(. I was too busy playing warcraft! Strange how people as far as Oxfordshire have heard this! It's also on the bbc site. I only found out about this from my friends on facebook.
