AFP through Getty ImageA sonic boom has been reported in some parts of England.
Loud bang was heard at around 11:35 BST in Essex, Cambrishire and Safok.
An RAF spokesperson confirmed the quick response warning (QRA) aircraft, but it was said this morning: “As it is an ongoing mission, no additional details will be given until it is completed.”
A sonic boom occurs when an aircraft travels faster than the speed of sound, causing shockwaves that rapidly compress and disintegrate the air, leading to explosive noise.
While the speed of sound varies depending on the height, it is about 660mph (1,060 km/h) at 60,000 feet (18,300 m).
The sound, often described as an explosion or thunderclap, can be heard in a large area because it moves along the aircraft, in view of the boat spread behind a pot.
