A sonic boom which shook huge areas of Suffolk this morning was caused by Typhoon jets taking a Ryanair plane to Stansted Airport, the Ministry of Defence has confirmed.
Thousands of people in the county said they heard a large bang at around 8.35am.
People living in Ipswich, Haughley, Great Barton and Bury St Edmunds are among those who have reported hearing the noise.
Police in Suffolk have been inundated with calls from residents about the boom, caused by Typhoon fighter jets passing through the county after a security alert on board a Ryanair plane.
The airline has since confirmed the security alert, which stopped flights for around 10 minutes, was a hoax.

Armed police were spotted at the airport and Essex Police said officers were investigating.
An RAF spokesman said: “The RAF can confirm Quick Reaction Alert Typhoon aircraft were launched this morning from RAF Coningsby to intercept a civilian aircraft.
“The aircraft was safely escorted to Stansted Airport.
“The Typhoon aircraft were authorised to transit at supersonic speed for operational reasons, any inconvenience caused to local residents is regretted.”
A Suffolk police spokeswoman said this morning: “We have had several people ringing us saying they heard an explosion, callers were from west Suffolk, east Suffolk and Ipswich.
“We can confirm that the loud bang was a sonic boom produced by military aircraft.”
A sonic boom is the sound associated with the shock waves created by an object travelling through the air faster than the speed of sound.
People living on the Suffolk/Norfolk border, in towns such as Diss, have also reported hearing the boom.
Residents in north Essex, in towns such as Harwich, also heard the noise.
Gary Avis wrote on Twitter: “Unbelievable big bang or explosion heard mid-Suffolk?? What was it, it just shook the barn!”
While Hayley Shireen said: “Huge bang heard in Haughley, shook the entire house.”
