William at 40: A milestone birthday in a life under scrutiny

FILE - Britain's Queen Elizabeth II is escorted by Prince William, during a visit to RAF Valley, Anglesey, Wales, where he is stationed as a search and rescue helicopter pilot, Friday April 1, 2011. The world watched as Prince William grew from a towheaded schoolboy to a dashing air-sea rescue pilot to a father of three. But as he turns 40 on Tuesday, June 21, 2022, William is making the biggest change yet: assuming an increasingly central role in the royal family as he prepares for his eventual accession to the throne.
