The twin jet plane en route to Denver from Hong Kong is merely a green radar blip half an hour off the California coast when the call comes through to air traffic control: 'Socal Approach, this is TransPacific 545. We have an emergency.' The pilot requests priority clearance to land - then comes the bombshell - he needs forty ambulances on the runway.
