In the unlikely event... And... Government regulations require that we inform you.

 No mention was ever made of urgency, should the equipment be required for use.

As a result, passengers became as indifferent to emergency oxygen facilities as airlines and their staffs appeared to be. The overhead boxes and monotonous, always-alike demonstrations were (passengers reasoned) something dreamed up by a bunch of regulation-obsessed civil servants. (Yawn!) Obviously the whole thing was largely a charade, insisted on by the same kind of people who collected income taxes and disallowed expense accounts. 

So what the hell!

Occasionally, on regular flights, oxygen mask housings opened accidentally, and masks dropped down in front of passengers. When this happened, most passengers stared curiously at the masks but made no attempt to put them on. Precisely that reaction---though the emergency was real---had occurred aboard Flight Two.

Vernon Demerest saw the reaction and in a flash of sudden anger remembered his own, and other pilots', criticisms of soft-pedaled oxygen announcements. But there was no time to shout another warning, nor even to think of Gwen, who might be dead or dying only a few feet away.

Only one thing mattered: somehow to get back to the flight deck, and help save the airplane if he could.

Breathing oxygen deeply, he planned his movement forward in the aircraft.

Above every seat section in the tourist cabin, four oxygen masks had dropped---one for the occupant of each seat, plus a spare to be grabbed if necessary by anyone standing in the aisle. It was one of the spares which Demerest had seized and was using.

But to reach the flight deck he must abandon this mask and use a portable one that would permit him to move forward freely.

He knew that two portable oxygen cylinders were stowed, farther forward, in an overhead rack near the first class cabin bulkhead. If be could make it to the portable cylinders, either one would sustain him for the remaining distance from the bulkhead to the flight deck.

He moved forward to the bulkhead one seat section at a time, using one spare hanging mask after another as he went. A couple of seat sections ahead, he could see that aff four masks were being used by seated passengers; the three seat occupants, including a teen-age girl, had one mask each; the fourth mask was being held by the teenager over the face of an infant on its mother's lap alongside. The girl seemed to have taken charge and was motioning to others near her what to do. Demerest swung toward the opposite side of the cabin, saw a spare mask hanging, and taking a deep breath of oxygen, he let go the one he had and reached for the other spare. He made it, and breathed deeply once again. He still had more than half the tourist cabin length to go.

He had made one more move when he felt the aircraft roll sharply to the right, then dive steeply down.

Demerest hung on. He knew that, for the moment, there was nothing he could do. What happened next was dependent on two things: how much damage the explosion had done, and the skill of Anson Harris, at the flight controls, alone.

ON THE FLIGHT deck, the events of the last few seconds had occurred with even less warning than at the rear. After the departure of Gwen Meighen and Mrs. Quonsett, followed by Vernon Demerest, the two remaining crew members---Anson Harris and Second Officer Cy Jordan---had no knowledge of what was going on in the passenger cabins behind them until the dynamite blast rocked the aircraft, followed an instant later by explosive decompression.

As in the passenger compartments, the cockpit filled with a thick, dark cloud of dust, almost immediately sucked out as the flight deck door smashed free from its lock and hinges, and flew outward. Everything loose on the flight deck was snatched up, to be carried back, joining the debris-laden whirlwind.

Under the flight engineer's table, a warning horn began blaring intermittently. Over both front seats, bright yellow lights flashed on. Both horn and lights were signals of dangerously low pressure.

A fine mist---deathly cold---replaced the cloud of dust. Anson Harris felt his eardrums tighten painfully.

But even before that, he had reacted instantly---the effect of training and experience of many years.

On the long, uphill road to airline captaincy, pilots spent arduous hours in classrooms and simulators, studying and practicing airborne situations, both normal and emergency. The objective was to instill quick, correct reactions at all times.

The simulators were located at important air bases and all major scheduled airlines had them.

From outside, a simulator looked like the nose of an aircraft, with the rest of the fuselage chopped off; inside, was everything included in a normal flight deck.

Once inside a simulator, pilots remained shut up for hours, imitating the precise conditions of a long distance flight. The effect, when the outside door was closed, was uncanny; even motion and noise were present, creating the physical effect of being airborne. All other conditions paralleled reality. A screen beyond the forward windows could conjure up airports and runways, enlarging or receding to simulate takeoff and landing. The only difference between a simulator flight deck and a genuine one was that the simulator never left the ground.

Pilots in a simulator conversed with a nearby control room, as they would on radio in the air. Within the control room, skilled operators duplicated air traffic control procedures and other flight conditions. The operators could also feed in adverse situations, without warning, to pilots. These ranged through multiple engine failure, to fire, violent weather, electrical and fuel problems, explosive decompression, instrument malfunction, and other assorted unpleasantness. Even a crash could be reproduced; sometimes simulators were used in reverse to find out what bad caused one.

Occasionally an operator would feed in several emergencies at once, causing pilots to emerge later, exhausted and sweat-drenched. Most pilots coped with such tests; the few who didn't had the fact noted in their records, were re-examined, and afterward watched carefully. The simulator sessions continued, several times a year, through every stage of a pilot's career until retirement.

The result was: When a real emergency occurred, airline pilots knew exactly what to do, and did it, without fumbling or loss of precious time. It was one of many factors which made travel by scheduled airlines the safest means of transportation in human history. It had also conditioned Anson Harris to instant action, directed toward the salvation of Flight Two.
