Sonic boom also heard a bit further afield.
A sonic boom has been heard and felt by residents in London, Essex and Cambridge.
It is thought to have been caused by an RAF Typhoon fighter jet flying south over Cambridge.
A sonic boom is the sound associated with the shock waves created whenever an object travels through the air faster than the speed of sound.
Twitter user Guy Aglionby tweeted a graphic from aircraft tracker ADS-B Exchange which appeared to show a fighter jet travelling south from Lincolnshire.
