A resident has complained of a “great big bang” in Liverpool.
One person tweeted: “Anyone hear an explosion in Liverpool just now? Great big bang.”
Amid the concerns about the “explosion”, one Twitter user responded to point out it was likely a sonic boom.
They tweeted: “Just been a fighter jet gone over Liverpool.
“Probably a sonic boom.”
It is believed the “great big bang” was heard in Aintree, Sefton and Clubmoor in Liverpool, which are four miles apart.
FlightRadar24 website showed a jet was flying over the area at the time the sound was heard.
A sonic boom happens when an object travels through the air faster than the speed of sound.
The boom is the sound associated with the shock waves created by the speed.
Sonic booms generate huge amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.
In order to smash the sound barrier, an aircraft would need to reach a speed of 770mph.
This latest sonic boom comes after a number of incidents across the UK over the last few months.
Last month, people in Cornwall reported their houses “shook” following a sonic boom caused by an RAF aircraft.
Back in January, people in Norwich heard a sonic boom caused by a military jet doing a dive.
Another explosion was heard over London and Cambridge in early January.
