Building it would be no small undertaking, and failure could mean the end of the Airbus. This is the story of the A380, from its planning to its building to its first big test. It was a high-stakes gamble, with engineering and logistical challenges on a scale never seen before. Engineers wondered if a plane this size could ever get off the ground, and they risked everything to find out.
