Then came the delicious moment of soaring upward—the ecstasy of feeling himself borne through the air as swiftly as the arrow from an archer’s bow and that sense of wonderful freedom which the airman alone can enjoy.

He could see the students and instructors, watching, it seemed to him, with an interest and close attention that fired his spirit with the keenest determination to make a landing that would surprise them.
