QuoteA loud bang which sparked a deluge of calls to emergency services across a large part of England was a sonic boom from a Typhoon aircraft, the MoD said.

I thought this was strange, I would believe the MOD if the boom wasn't heard over such a large area, what do you think DD? Do you belive the MOD's explanation?

Sonic booms can be heard over large distances, it depends a lot on weather conditions and geography as to how the sound carries.

Lincolnshire is pretty flat so I suppose it would assist the carry, all the places that the boom was heard are to the East of Lincolnshire which was the direction of travel of the aircraft and also the prevailing wind would be going that way too.

It's possible, but seem to be a very large area.

Yeah, I guess it is possible, it struck me as odd that there was only one boom but two aircraft, I guess if both boomed at exactly the same time it would be louder.

Sounding more feasible.

Not to mention that we aren't used to sonic booms over the UK as usually military aircraft are only allowed to go supersonic once out to sea.

Perhaps it's because of the era, when I was growing up, and the location, as well, but we experienced several sonic booms per month near my home in Northern California, often at VERY close range (less than a mile), and often created by more than one aircraft at a time. The pilots on training maneuvers would use the narrow passes and long valleys in the area near my home to test their radar avoidance skills, so it wasn't unusual to see a pair of jets flying less than 300 feet above us zoom by, only barely sub-mach, and then kick in the afterburners as they entered the valley. Watching them pass by was a thrill for a 12 year old (as I was at the time), and even more so to see the effects of the sonic boom, making the pine trees around me shiver and quake when the shock wave passed us. With all of the noise restrictions in place today, the NOE (Nap Of the Earth) flights no longer occur there, and I could understand how folks would call something like that in, if they had never experienced it, but for me, it's not a big deal. :) In fact, I realize now that I actually miss that sort of thing. :P

I've seen the RAF doing low flying pratcice in the hills and valleys of Dartmoor in Devon and alos in the Pennine Mountains in Yorkshire.

Seeing Tornados flying at low level below you (was hiking in the mountains at the time) was pretty special.
