On the 4th of November 2010, a Qantas Airbus A380 was rocked by a catastrophic engine failure minutes after takeoff from Singapore, hurling fragments of a turbine disk through its wings and fuselage in multiple locations. The explosion damaged almost every major system on the airplane, from the flight controls and fuel tanks to hydraulics and pneumatics. Faced with a barrage of diverse failure warnings and an airplane of uncertain integrity, the flight crew worked together to make a series of critical decisions that would get their enormous airplane back on the ground. And in the end, despite one curveball after another — including landing gear problems, loss of braking power, and an engine that refused to shut down — they not only landed the plane, but did so without putting a scratch on any of the 469 passengers and crew.

The cause of the incident would ultimately be traced deep inside the number two engine to a single oil pipe that had been manufactured with a wall that was slightly too thin. How this seemingly tiny defect came about, and how it nearly brought down the world’s largest passenger plane, represent a story equally as fascinating as that of the flight itself, tracing back years to encompass questionable drawing board decisions, hidden flaws in the machining logic, and faulty assumptions about engine behavior. Time and time again, the problem slipped through the gaps in the system, tumbling down the long slope toward disaster — only to be stopped at the last moment, not only by the pilots themselves, but by a number of explicit protections built into the design of the A380, each of which played a crucial role in containing the fallout from a failure that exceeded the manufacturer’s worst expectations. The story of Qantas flight 32, as told herein, is therefore not only the tale of a dramatic emergency, but a testament to the safety of aviation today — a story that should make every reader feel a little less fearful of flight.
