What's an heir to the throne with a newly announced princess at his side to do while the world awaits the glamorous nuptials? Why, save lives of course. 

After a hiker on the 3,560-foot Mt. Snowdon in Wales suffered a heart attack last Thursday, the Royal Air Force was called in to perform a rescue operation. At the controls of that helicopter — and piloting the craft through thick fog — was none other than the 28-year-old prince. 

The 45-year-old victim, Greg Watkins, told the U.K.'s Sunday Mirror he owes his life to William and his team.

"If it wasn't for him and the rest of his crew, I'd be dead," Watkins said. "He'd probably say he was just doing his job but, to me, he and his crew are heroes."

"I didn't know Prince William was flying the helicopter until we landed at the hospital," added Watkins. "Even then I felt too unwell for it to really register. The winchman helped me out and on to a stretcher then whispered, 'Prince William's just flown you here.' I looked up at him and just said, 'Oh. Tell him thank you.' It didn't really sink in until I woke up after my operation. Now I think it's amazing."

According to the British press, William and Kate are said to be planning an April 28th wedding. No doubt, Watkins will be sending the couple something special to help celebrate the occasion.
