Maybe it's just all hype... I dunno.
I can't give you a precise distance because the sound pressure level created and distance the sonic boom will be heard will depend upon the size and shape of the object (aircraft, meteor), its height and speed, atmospheric conditions, and weather conditions. In addition, propagation along the ground once the sound waves reach the surface, depends on whether the surface is land or open water. 30 to 60 miles is typical for sonic booms created by fighter aircraft over land, but faintly audible sonic booms have been heard as much as 300 miles from their source.

Sonic boom is the "official" line.
I was directly under one once. nearly had a heart attack, never shook my house.

Well i did not hear it i was driving on the M4 at the time however
what i find odd is ok the story is a typhoon called on to intercept
a Civilian Helicopter that had (in error) hit a "ive been hijacked help button"
ok first point is there such a thing as an emergency button that tells the plane to emit
such a signal? via its transponder i assume on NON military A/C .
and AFAIK NO aircraft military or otherwise is allowed to go supersonic over the UK landmass
and out to 10 NM of the coast for any reason what so ever period end of (outside of wartime manoeuvring)
due to the enormous amount of complaints and reports that come flooding in as today has shown
not to mention the possible claims that could arise.
This is why Concorde always stayed below the sound barrier until well off the Cornish or Irish coast.
which is why that u tube vid of concord's boom's was taken from a boat it was the only way you COULD
hear it.
I think there "might" be more going on here than we are being told!

There is a mobile phone video on BBC TV news, which oddly shows a whilte flash across the sky at the same time as the boom if anyone is able to upload it. It was heard from Warwickshire to Oxfordshire, Wiltshire and Somerset, these counties aren't all in close proximity and all heard at the same time, over hundreds of miles. There are air shows here every year and with typhoons flying with sonic booms and it has never caused a fuss in even near counties.
