Sir George visited the Thames Valley Air Ambulance
on Wednesday with Lady Young to thank paramedics for rescuing his toddler grandson after he fell in a swimming pool.
Sir George Young took his grandson Alexander Butler, now four, to see the air ambulance helicopter at its base in White Waltham.
Alexander was just two-years-old when he fell into the swimming-pool at his parents' home in Mill Lane, Cookham in September 2001 - where Sir George grew up.
Alexander's grandmother Aurelia Young described the ordeal "He was floating on his back and his lips were blue so I jumped in and pulled him out," she said. "Mercifully he still had his jacket on so the air was holding him up."
Lady Young called an ambulance and put him in the recovery position while it was on its way.
"There was this tremendous noise and all the trees were swaying and cracking, then we saw this helicopter and it was just wonderful," she said.
"They took him in the helicopter to Wexham Park Hospital with his mother and thankfully there was happy ending. We were just so grateful. It was such wonderful relief." The helicopter arrived in about four minutes, three times as quick as the journey by road. Air ambulance fundraising director Stevie Horton said she was thankful the helicopter was available to rescue Alexander.
The air ambulance crew completed their 100th mission for the month of May, on Wednesday. Pilot Neil Parkinson said that was a record for a month
