Prince William (L) alongside his instructor Squadron Leader Roger Bousfield (R) walk past the squandron insignia as they prepare to go flying while training at airbase RAF Cranwell, near Sleaford, Lincolnshire 17 January 2008. The prince, an army officer with the Household Cavalry's Blues and Royals, is two weeks into a four-month attachment with the RAF to help William, 25, get to grips with the service's ethos, traditions and military role. The prince's father, Prince Charles, completed his flying training course at RAF Cranwell from March to August in 1971 and graduated that year as a Flight Lieutenant. While training with 1 Squadron of 1 Elementary Flying Training School he will fly a propeller driven Grob 115E light aircraft, known as the Tutor. If successful he will move to 1 Flying Training School where he will get to grips with the faster Tucano T1 plane and finally progress to fly the Squirrel helicopter.
