Two RAF Typoon Jets were launched from RAF Coningsby on Thursday morning after a reported bomb threat.
A sonic boom was heard across Derbyshire as military aircraft were sent to intercept a passenger plane, which was diverted to Stanstead Airport. The Air India Boeing 777 was flying from Mumbai in India to Newark in the US.
Police and the fire service reportedly received “a large number” of 999 calls from people who feared there had been an explosion, with some residents saying their homes shook. A loud bang was heard shortly before 10am BST.
The runway has now reopened at Stanstead Airport and is fully operational.
#UPDATE Our runway has now re-opened and is fully operational following a precautionary landing of Air India flight.
We are sorry for any disruption caused by the incident and would like to thank you for your patience.
