Fighter jets in Olympic security exercise

Fighter jets will soar across Britain to test Olympic security.

The Ministry of Defense said Typhoon fighter jets from around the country will arrive at a Royal Air Force base at Northolt in west London for an eight-day military exercise beginning Wednesday. They will return to their bases after the exercise but will come back to Northolt for the duration of the games, July 27-Aug. 12 and then the Paralympics, from Aug. 29-Sept. 9.

The Royal Air Force will also send Puma transport helicopters and Lynx helicopters carrying teams of snipers trained to intercept aircraft flying without authorization in London airspace.

Soldiers on the ground are testing out missile systems that may be based on buildings and apartment blocks near the Olympic site.

Defense secretary Phillip Hammond said there is no specific threat relating to the games.
