Twenty five years ago, United Airlines Flight 232 slammed onto a runway in Iowa and burst into flames. Miraculously, 184 of 296 passengers lived. Laurence Gonzales, a commercial pilot, draws on interviews with hundreds of survivors, crew, and airport and rescue personnel, to tell the harrowing story of pilots flying a plane with no controls and flight attendants keeping their calm in the face of certain death. His book Flight 232: A Story of Disaster and Survival goes step by step through the research that reveals the flaw, smaller than a grain of rice, that brought down the aircraft.
