From my local rag"
Eight out of the 16 sonic booms recorded in the UK in the last five years were over Wales - with four heard in Ceredigion alone.
Car windows have shattered, roof tiles have fallen and greenhouses have been damaged because of the booms, which are caused when an aircraft breaks the sound barrier.
The information has come to light following a Freedom of Information request submitted to the Ministry of Defence.
Broken a car windscreen? Really? I'm sure a zoomie or former zoomie will be along soon to put a realistic view.
Whilst on the subject: what is the relationship between the aircraft and the 'hearer'? When does the hearer hear the bang? Is it dependent on aicraft height, Mach number etc?
Only interested. Ta.
