At Aden Abdulle International Airport the chaos starts at 06.30. The outermost steel security boom is raised and the stream of passengers makes its way through five separate security checkpoints and flows on past the blast walls and barbed wire into the concrete terminal. Midway through the morning rush, airport worker Abdul Kani takes stock of the familiar scene. The dim, low-ceilinged room is engulfed in a sea of passengers. They form in human eddies around the seven check-in counters, jostling, shouting and sweating, teeth gritted as they wave their tickets in the air.
