"I thought we were going right down that time." "You hold tight!" yelled Dick.

"Don't let go for an instant." "I'm as tight as glue," was the reply.
"Hadn't you better go up a bit, Dick ?" came from Tom.
"Just what I thought of doing," was the answer.
The rudders were shifted, and swiftly the biplane mounted through space.
It was now growing dark, and presently the panorama that had been below them, vanished from view.
"Huh! This won't do!" cried Dick.

"I can't see how to steer." "Steer by the wind for awhile," suggested Sam.
A minute later came a fierce gust of wind, followed by a second and then a third.

Around spun the biplane and then tilted up as if about to go over.

Then came an unexpected ripping and tearing sound.
"It's the left plane--it's torn loose!" yelled Sam.
