pounded on to the sheet of paper in the typewriter. The newcomer, summoned by the bell, was the airport controller, a tall, lean man who had spent a lifetime in the air and knew the conditions of travel over the northern hemisphere as well as he knew his own back garden. Better, in fact, for didn’t his onions always run to seed? He got halfway through the message, then stepped sharply back, cracking an order over his shoulder to the telephone operator on the far side of the room.
“Get me Air Traffic Control quickly. Then clear the teletype circuit to Winnipeg. Priority message.” The controller picked up a phone, waited a few seconds, then said, “Vancouver controller here.” His voice was deceptively unhurried. “Maple Leaf Charter Flight 714 from Winnipeg to Vancouver reports emergency. Serious food poisoning among the passengers, and I mean serious. The first officer is down with it too. Better clear all levels below them for priority approach and landing. Can do? Good. ETA is 05.05.” The controller glanced at the wall dock; it read 02.15. “Right. We’ll keep you posted.” He pushed down the telephone cradle with his thumb, keeping it there as he barked at the teletype operator, “Got Winnipeg yet? Good. Send this message. Starts: ‘Controller Winnipeg. Urgent. Maple Leaf Charter Flight 714 reports serious food poisoning among passengers and crew believed due to fish served dinner on flight. Imperative check source and suspend all other food service originating same place. Understand source was not, repeat not, regular airline caterer.’ That’s all.” He swung round to the telephone switchboard again. “Get me the local manager of Maple Leaf Charter. Burdick’s his name. After that I want the city police — senior officer on duty.” He leaned over the radio operator’s shoulder again and finished reading the now completed message. “Acknowledge that, Greg. Tell them that all altitudes below them are being cleared and that they’ll be advised of landing instructions later. We shall want further news later of the condition of those passengers, too.”
On the floor below, an operator of the Government of Canada Western Air Traffic Control swiveled in his chair to call across the room, “What’s in Green One between here and Calgary?”
“Westbound. There’s an air force North Star at 18,000. Just reported over Penticton. Maple Leaf 714—”
“714’s in trouble. They want all altitudes below them cleared.”
“The North Star’s well ahead and there’s nothing close behind. There’s an eastbound Constellation ready for take-off.”
“Clear it, but hold any other eastbound traffic for the time being. Bring the North Star straight in when it arrives.”
Upstairs, the controller had scooped up the telephone again, holding it with one hand as the other pulled at his necktie, worrying the knot free. Irritably he threw the length of red silk on the table. “Hullo, Burdick? Controller here. Look, we’ve got an emergency on one of your flights — 714 ex Toronto and Winnipeg. Eh? No, the aircraft’s all right. The first officer and several passengers are down with food poisoning. I called Winnipeg right away. Told them to trace the source of the food. Apparently it isn’t the usual caterer. No, that’s right. See here, you’d better come over as soon as you can.” He jabbed the telephone cradle again with his thumb and nodded to the switchboard operator. “The police — got them yet? Good, put them on. Hullo, this is the controller, Vancouver Airport. Who am I speaking to, please? Look, Inspector, we have an emergency on an incoming flight. Several of the passengers and one of the crew have been taken ill with food poisoning and we need ambulances and doctors out here at the airport. Eh? Three serious, possibly others — be prepared for plenty. The flight is due in just after five o’clock local time — in about two and a half hours. Will you alert the hospitals, get the
