A 94-year-old man from Solihull is taking part in a wing-walk in memory of Stephen Sutton.
Over the years Tom Lackey has done a number of high-flying plane stunts, but he says he's been inspired to do one more by Stephen's story.
The 19-year-old from Burntwood in Staffordshire lost his battle with bowel cancer this week.
His Just Giving page has now raised nearly £3,900,000 for the Teenage Cancer Trust.
On Thursday the dare-devil pensioner will carry out his 30th wing walk, travelling from Lands End to the Isles of Scilly strapped to the top of a plane.
Speaking at his home, the 94-year-old paid an emotional tribute to Stephen, saying he would have his thumbs up in the air for the teenager while carrying out the stunt, imagining the 19-year-old's up there with him.
