From the moment a Japan Airlines passenger jet collided with a smaller plane on a runway in Tokyo on Tuesday, it took a 12-member crew 18 minutes to get all 367 travellers off the plane and safely accounted for. Reconstructing the scene based on crew accounts, officials at Japan's second-biggest airline said crew followed emergency procedures in textbook fashion, starting with the first rule: panic control. As soon as the Airbus A350 wide-body jet came to a stop, cabin attendants called out to passengers to remain calm.
