Panic Over Sonic Boom in the UK: RAF Typhoon Jet Reaches Supersonic Speed

The cause of a powerful sonic boom heard in the skies over eastern and southeastern England on Friday morning has been revealed. The Royal Air Force (RAF) scrambled three Eurofighter Typhoon FGR4 jets from RAF Coningsby in Lincolnshire to intercept a passenger aircraft that had lost contact with air traffic control.

According to flight tracking data, one of the Typhoon jets reached a speed of 700 knots (805 mph) at around 11:40 a.m. at an altitude of approximately 40,000 ft. As the aircraft exceeded the supersonic speed threshold, a loud explosion-like sound was heard across Kent and Essex.

An RAF spokesperson said:

“A Typhoon fighter jet from RAF Coningsby was dispatched to investigate a civilian aircraft that had lost contact with air traffic control. Communication was re-established, and the aircraft was safely escorted to Stansted Airport.”

Essex Police also confirmed that there was no security threat from the passenger plane. The aircraft, reportedly departing from Nice, has not yet explained why communication was lost.

Experts noted that the sonic boom occurred because the aircraft exceeded the speed of sound (approximately 1,221 km/h), generating shock waves in the atmosphere that produced the intense explosion-like noise.

The RAF uses Typhoon FGR4 jets for a wide range of missions, including air policing, peacekeeping, and high-intensity conflict operations.
