Sonic boom-like sound leaves Norfolk residents baffled as Ministry of Defence says no RAF Fast Air were in area

Norfolk residents have been left perplexed after the sound of an explosion rattled the county.

The bang - which many suspect to have been a sonic boom - was heard at around 12.30pm yesterday in places including Lynn, Downham, Marham, South Pickenham, Wretton, Shouldham, Nordelph, Upwell, Stow Bridge and even as far as March.

“I thought a lorry had gone through my house,” one Facebook user commented.

Another added: “I thought it was going to take my doors off.”

Despite this, a spokesperson for the Ministry of Defence has said there were no reports of RAF Fast Air aircraft in the vicinity, however, enquiries are still ongoing.
