You can't help but have the feeling that there will come a future generation of men, if there are any future generations of men, who will look at old pictures of helicopters and say, "You've got to be kidding."

Helicopters have that look that certain machines have in historical drawings. Machines or devices that came just before a major breakthrough. Record-changers just before the lightweight vinyl LP for instance.

Mark Twain once noted that he lost belief in conventional pictures of angels of his boyhood when a scientist calculated for a 150-pound men to fly like a bird, he would have to have a breast bone 15 feet wide supporting wings in proportion. Well, that's sort of the way a helicopter looks.

The thing is helicopters are different from airplanes. An airplane by its nature wants to fly, and if not interfered with too strongly by unusual events or incompetent piloting, it will fly. A helicopter does not want to fly. It is maintained in the air by a variety of forces and controls working in opposition to each other. And if there is any disturbance in this delicate balance the helicopter stops flying immediately and disastrously.

There is no such thing as a gliding helicopter.

That's why being a helicopter pilot is so different from being an airplane pilot, and why in generality airplane pilots are open, clear-eyed, buoyant, extroverts. And helicopter pilots are brooders, introspective anticipators of trouble. They know if something bad has not happened, it is about to.
