A massive explosion was heard in London and Cambridge from a fighter jet’s sonic boom.
Residents have described their houses ‘rocketing’ and ‘shaking’ after the jet ‘made a hell of a bang’.
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.
Cambridge City Council tweeted: ‘If you heard a massively loud bang over Cambridge in the last few minutes, don’t panic – apparently it was the sonic boom from a fighter plane breaking the sound barrier!’
Many people took to Twitter to share their reactions to hearing the noise.
One person tweeted: ‘RAF Typhoon just made one heck of a sonic boom over Cambridgeshire. Nearly fell out of my chair.’
Another said: ‘It was so loud I thought my other half had crashed through the patio doors!’
A third said: ‘Sounds like the whole Romford area felt it, whole house shook and you could feel it in the ground.’
They added: ‘Sonic boom makes sense, my first thought was that nearby construction collapsed.’
Others joked the sound was ‘the most thrilling thing to happen in 2021’ while a teacher said the noise interrupted her live lesson.
Ex Army reservist and former Cambridge councillor Zoe O’Connell said the sonic boom was likely deliberate in order to intercept another jet.
Sky news correspondent Alistair Bunkall said two RAF Typhoons were launched from Coningsby to intercept a private jet that lost communications.
He said the jets were authorised to fly supersonic, causing the boom over the Cambridgeshire area.
He added: ‘Jet escorted safely into Stansted. Incident now over.’
