Both Thompson and Colburn were interviewed for the film "Four Hours in My Lai" (1989) ("Remember My Lai?" on PBS) – which went on to win a British Academy Award and an international Emmy award. The interview showed Thompson relating what he had witnessed at Mỹ Lai: "Here we were supposed to be the guys in the white hats. It upset me". Bilton and his colleague Kevin Sim then began researching a book and Bilton conducted further interviews with Thompson and Colburn. When the book "Four Hours in My Lai" (1992) was published, it prompted a campaign to have the heroism of Thompson and his helicopter crew recognised. Several senior figures in the U.S. military supported the campaign, as did President George H. W. Bush. Thompson and Colburn were invited to speak to a wide range of audiences about the ethics of warfare including at West Point, a conference in Norway, and at Connecticut College in New London, where they were each awarded an honorary doctorate.
