Captain Tom salutes the RAF flyby to celebrate his birthday

The RAF carried out a special birthday aerial salute to Captain Tom with old spitfire and hurricane planes joining a flypast of his home in Bedfordshire, and even the Prime Minister sent him a message of good wishes, saying: "Your heroic efforts have lifted the spirits of the entire nation."

Tom has been typically modest with all the attention, he told the BBC: "It hardly feels any different than yesterday. I don't know what you're meant to feel like when you get to be 100.

"I've never been a hundred before so I really can't tell you what difference there is from yesterday, today or maybe tomorrow but I must say I'm absolutely delighted with all the people who've been so kind to make those remarks. Thank you all very much."
