****** loudest crack of thunder I've heard in a while today.
As it was forecast thunder this week I didnt think anything of it until I watched the news tonight.
It wasnt thunder.
It was two typhoon military aircraft going supersonic over the West Midlands !!
We can confirm that a small civilian aircraft was transmitting inadvertently on an emergency frequency at approximately 1810. Two typhoons from the Quick Reaction Alert (QRA) responded accordingly and authorisation was given from them to go supersonic which resulted in the sonic boom. There was no actual threat to the civilian aircraft and they soon rectified their mistake.– Ministry of Defence
