From the BBC http://news.bbc.co.uk/1/hi/uk/3691856.stm A plane has landed safely at Stansted Airport in a major security alert. An unspecified number of RAF planes were scrambled after Olympic airline flight OA411 from Athens to New York asked to be diverted to Stansted. It landed at 1529 GMT and the RAF planes have now returned to base after the incident was concluded "safely", according to the MOD. All 301 passengers and crew have been evacuated safely and the plane is now being comprehensively searched 'Full emergency conditions' A spokesman for Stansted Airportsaid the plane landed under "full emergency conditions." The BBC's Athens correspondent Richard Galpin told BBC News 24 the incident happened after an elderly man called a Greek newspaper anonymously and told them there was a bomb on board. The paper called the police, who called the airline. No code word is believed to have been used. All 290 passengers and 11 crew members have been taken off the plane. The RAF is not releasing any more details of how many of its planes were involved for security reasons. An MoD spokesman said the pilot contacted air traffic controllers for help. Officials contacted the Department of Transport and then the MoD gave the go-ahead to escort the plane. A spokesman for the Department for Transport said the aircraft "is on the ground and being searched as part of a standard response". "It is not believed to be anything out of the ordinary at this stage." "These are rehearsed procedures which have swung into action. "Fortunately nothing has exploded, if indeed there was a bomb on board, but we take all threats seriously."
