In this episode, it's a day of firsts at the airport. For the first time ever, both runways are being closed back to back, in a billion-dollar reconstruction programme. We follow them on the first day of the North Runway closure, which has come off the back of almost a month of work on the South Runway. Also for the first time, Emirates Airlines bring in the first Airbus A380 that they bought six years ago, for a thorough maintenance check. We'll see the aircraft put up on jacks, engines being stripped and the cabin gutted. Meanwhile, trainee Hamid prepares to begin his first ever solo push-back of a heavily laden jet plane, and Mel Sabharwal encounters a passenger travelling with a fake passport, who tries to outfox her by dodging her questions.
