Prince William's dreams of learning to fly are about to come true as he gets ready to start training as a pilot.
From Monday, he'll be taught how to fly planes and helicopters during a four-month attachment with the Royal Air Force in Lincolnshire.
RAF pilot training normally takes up to four years, but a shorter course has been designed just for the Prince.
As he'll be head of the armed services when he's older, he's trying to get experience with all three services.

He's already spent a year in the Army and is expected to spend time with the Royal Navy later in the year.
RAF instructors said William's course was "tough but achievable".
"We have adapted the course because we're not teaching him to be an operational pilot, we're teaching him to be a competent pilot," they said.
"It's going to be pretty tough. We expect him to work five days a week, he'll be flying probably twice a day and he'll have study to do in the evenings as well."
