On November 4, 2010, four minutes after takeoff from Changi Airport in Singapore, the number two jet engine of Qantas Airways flight QF32 exploded. On board the Airbus A380 were 440 passengers, 24 crew members in the cabin, and three captains and two copilots in the cockpit. Debris from the exploded engine hit the left wing, destroying a number of electrical and hydraulic lines. Thereafter, several essential aircraft control systems failed. Over the next harrowing two hours, the pilots flew in a holding pattern. They needed to burn enough fuel so that the plane’s final weight would allow for a safe landing.
