This is the sound of a sonic boom.
Two loud bangs were heard across central eastern UK on May 2, as two Typhoon jets from RAF Coningsby were scrambled to intercept a Cityjet Avro RJ-85 that was flying as Air France 1558 from Paris Charles de Gaulle, France, to Newcastle, UK.
The RJ-85 failed to reply to the ATC (Air Traffic Control) calls prompting the British Air Defense to scramble two Typhoons in QRA (Quick Reaction Alert) that intercepted the airliner and escorted it to landing.
To reach the “unresponsive civil plane” the two Typhoon fighters accelerated to supersonic speed causing the sonic booms that shocked several houses in parts of Yorkshire at around 21.50LT.
The following video was filmed by a surveillance camera in North Leeds. Turn your speakers on to hear the two loud bangs!
