Huge London ‘Explosion’ Trending on Twitter Was Sonic Boom, Authorities Say

Londoners were woken in the early hours of Sunday morning by a “loud bang” that authorities have said was a “sonic boom” caused by Royal Air Force planes.

People across the city took to social media to report they’d heard a loud noise at around 4.15 a.m. local time prompting “#explosion” to become the top trending topic on Twitter.

Authorities later confirmed that the noise had been caused by two RAF Typhoon fighter jets that took off from Coningsby in Lincolnshire to intercept an aircraft that was unresponsive.

The Metropolitan Police said there was “no cause for concern” after reporting the noise was the result of a sonic boom from RAF planes. “We are aware of reports of a loud bang in the north London area. There are no reports of an explosion and police are looking into the incident,” the force tweeted at around 4.45 a.m.

Around 15 minutes later, police added on Twitter: “The loud bang heard throughout north London and surrounding areas was the result of a sonic boom from RAF planes. There is no cause for concern.”
