In this Friday April 11, 2008 file photo, Britain's Prince William and his girlfriend Kate Middleton walk in RAF Cranwell, England after William received his RAF wings from his father the Prince of Wales. Prince William landed an air force helicopter at the home of his girlfriend's parents during a training flight, Britain's Defence Ministry confirmed Sunday April 20, 2008. British media on Sunday called the exercise wasteful at a time when the military is stretched by wars in Iraq and Afghanistan and warned it risked testing the public's patience with the monarchy.
