Matthew Sweet talks to the American writer, James Salter...although writer seems rather an inadequate description. He's been a fighter pilot, a rock climber and a film maker as well sitting at a desk staring at a blank page. His memoir Burning the Days came out in the UK in 1997 to huge acclaim and he's published some short stories since then as well but now, after a gap of 34 years, there's a brand new novel - All That Is. Matthew Sweet talks to him about the thrill of flying, women, grief and the consolations of fiction.
