Kirsty Young's castaway week is the aviator, inventor and arts patron, Sir Torquil Norman. He comes from a family where derring-do is in the DNA - his grandfather was a pioneering airman, his grandmother an adventurer and his father also a keen pilot. Torquil ended up in the toy trade where the skills needed were, he says, a close attention to detail combined with the outlook on life of a seven year old. He was, he admits, perfectly qualified. In retirement he set about his biggest project - he bought a disused railway engine shed and raised tens of millions of pounds to safeguard its future as a venue for performing arts and a centre for young people.
