Jane adjusted the straps of her parachute and Charlie boosted her into the cockpit of his biplane.

“If anything goes wrong,” he told her, “just bale over the side and after you’re clear, jerk the ring. Don’t worry about the ship. I made the movie people sign a guarantee to replace it, if anything should happen.”

“Nothing’s going to happen,” said Jane firmly.

“Atta girl. Let’s go.”

Charlie ran to the other plane and hoisted his long legs into the cockpit. Jane opened the motor of the biplane, waved to Miss Comstock, who was standing nearby, and then sped across the field.

It was a glorious summer morning and to the north and west the peaks of the majestic Rockies reared their heads above the clouds which obscured their lower levels. Jane tingled with the zest of her adventure. She was actually in the movies. Of course she was just doing a stunt, but when “The Sky Riders” came to Cheyenne she would have the pleasure of knowing that she had piloted one of the planes in an important piece of action.

Above Jane the first tri-motor, the plane she was to attack, was climbing steadily while the second of the big ships, with the director and main camera crew, was wheeling off the field. Charlie was already in the air, following her fast.

It took them fifteen minutes to get into position for action and at a signal from the director in the second tri-motor, the first plane lined away west, simulating a transport in regular flight. Jane, who was a thousand feet above the transport, jammed the throttle on full and dove for the big plane.

The wings of her biplane trembled under the crashing dive, but she knew the plane’s capabilities and her heart thrilled as she roared down on the big ship.

The machine gun spouted flame and smoke as she pulled the trigger. She flashed past the tri-motor, nosed up, and poured another volley of fake bullets at the big ship. Now the chase was on in earnest, the pilots of the tri-motor making every attempt to elude the pursuer and Jane was astounded at the tricky flying which could be done with one of the big transports.
