A passenger flight was diverted under military escort to Stansted Airport last night after a suspect package was discovered on board the flight, due to land at Coventry airport.
The holiday plane, carrying 103 passengers and travelling from Faro, in Portugal, was guided into the Essex airport by two Tornado F3 jets.
A Ministry of Defence spokeswoman confirmed all those onboard disembarked safely after landing.
She said: "At approximately 7pm, two fighter jets from RAF Coningsby were sent to escort a civilian aircraft to Stansted Airport. It landed at around
7.45pm, when the passengers disembarked safely."
Police confirmed the airport is operating normally, but have not yet revealed the nature of the suspect package.
A sighting of a suspicious object was reported by the aircraft crew and the plane was diverted as a precaution, an Essex police spokeswoman said.
She confirmed bomb disposal experts were examining the plane, which had been due to land at Coventry airport.
A spokesman for Essex police said last night: "At about 7.20pm this evening Essex police were alerted to a Boeing 737 Thomson flight 302 passenger aircraft en route to Coventry from Faro, in Portugal.
"A report had been received from aircrew that a suspicious object had been found in the cabin by a passenger."
A spokeswoman for Thomson Holidays, which was operating the Boeing 737, said the diversion was sparked when passengers spotted a mobile phone.
"It did not belong to any of the passengers or crew, the pilot was informed and put emergency procedures into action as a precaution," she said. "Air traffic control, police and the BAA were informed.
