Britain's Queen Elizabeth II (R) speaks with Stephen Nelson, Chief Executive of British Airports Authority, (BAA) as she opens Terminal 5 at Heathrow airport in west London, on March 14, 2008. Queen Elizabeth II unveiled a new terminal at London's main Heathrow airport Friday, under tight security a day after a major security scare disrupted flights. Terminal Five (T5) will be able to handle 30 million passengers a year, and opens as campaigners step up protests over plans for a third runway at the airport. It was unclear if Thursday's alert, in which a man scaled a perimeter fence and ran on to a runway, was designed as a protest. Police carried out a controlled explosion of two bags dropped by the man. Getty Images logo Getty Images 15 months ago
