There were some, however, whose eyes were eagerly rivetted on the indistinct figure of the flying girl and utterly disregarded the machine. Stephen, comfortably propped among the cushions of the motor car with his mother seated behind him and Sybil opposite, divided his attention between his sister and his creation. Mr. Cumberford, knowing what the machine would do, watched Orissa through a powerful glass and decided from the first that she was cool and capable. Chesty Todd also watched the girlish figure, with a more intense interest than he had ever before displayed during his brief and uneventful lifetime.

The reporter had been worried lest Mr. Cumberford neglect to warn the girlish operator of the Kane Aircraft of danger; so he pushed through the crowd about the hangar and just as Orissa passed the doorway, seated in her aëroplane, he said in a low voice: “Look out—for a collision!”

She started and cast an inquiring look at him, but there was no time to reply. The machine had been drawn by the assistants to a clear space and she must devote her attention to her work. As she threw in the lever Mr. Cumberford, who stood beside the aircraft, hurriedly whispered: “Be careful, Orissa—look out for danger!” Then she was off, facing the thousands on the field, with nerve and brain resolutely bent upon the task she had undertaken.

It was no indifferent thing this brave girl attempted. Until now her acquaintance with an aëroplane had been wholly theoretical; it was her first flight; yet so thoroughly did she understand every part of her air vehicle—what it was for and how to use it—that she had implicit confidence in herself and in her machine. Naturally level-headed, alert and quick to think and to act, Orissa was no more afraid of soaring in the air than of riding in an automobile. Aside from her desire to operate the aircraft so skillfully that her brother’s invention would be fully appreciated she was determined to attempt the winning of the ten thousand dollar prize, which would establish the Kane fortunes on a secure basis. Enough for one untried, seventeen-year-old girl to think of, was it not? And small wonder that she absolutely forgot the impressive warnings she had received.

The air is a mighty thoroughfare, free and untrammeled. The little group of aëroplanes operating over Dominguez—darting here and there, up and down—had little chance of colliding, for there was space enough and to spare. Orissa knew all about air currents and their peculiarities and she also knew that her greatest safety lay in high altitudes. With a feeling of rapturous exhilaration she began to realize her control of the craft and her dominance of the air. A masterful desire crept over her to accomplish great deeds in aviation.

Those who were watching from below—judges, friends and spectators—saw her steadily mounting, higher and higher, until she seemed to fade out of sight like the figure in a moving picture, with nothing but a little iron-and-wood skeleton and the chugging of a tiny engine to ward off death. Then she came into sight again, a little smudge of grayish white against the shifting clouds. To see her up there, a mere speck dodging among the storm clouds, reminded the observers, as nothing in aviation has ever done before, of the awful audacity of man in building these mechanical birds. As they watched they found themselves hoping—as a child might—that in some way the brave little speck would manage to escape those gigantic sky monsters. Then one seized the aircraft, and just as the sun caught and flung back to earth a flash from one of the busy propeller-blades a huge cloud swallowed up machine and aviator and they vanished like mist.

It was odd how the terror of the spectators increased at this sudden disappearance; they knew that somewhere in that awesome, infinite firmament a frail thing made by the hand of man was battling with nature’s most mysterious forces for supremacy. And man won. In less than a minute there was another flash of sunlight and the little gray speck emerged saucily from behind the cloud and made a dive for another.

Then the speck in the sky began to grow larger, and Orissa attempted an amazing dive earthward that caused the throng to fall silent, motionless, gazing with bated breaths and startled eyes at the thrilling scene. It was a long swoop out of space and into being; a series of dives half a mile long and each nearly straight down.

The girl glided earthward until the aircraft nearly touched the ground; then she adroitly tilted it up again and tore away around the course in great circles, while the spectators, roused to life, thundered their applause.

Her control of the aëroplane was really wonderful. Again, encouraged by her success, she shot up into the air, rising to the height of half a mile and then performing the hazardous evolution known to aviators as the “spiral dip.” She began by circling widely, at an even elevation, and then dipping the nose of the aircraft and narrowing the circles as she plunged swiftly downward with constantly accelerating speed. It was a bewildering and hair-raising performance, and no one but Walter Brookins had ever before undertaken it.
