"The big battle-plane, soaring fully two thousand feet above the earth, suddenly turned almost upside-down, so that its nose pointed at an angle close to forty-five degrees. Like a hawk plunging after its prey it sped through space, the two occupants held in their places by safety belts.
As they thus rushed downward the earth seemed as if rising to meet them. Just at the right second Tom Raymond, by a skillful flirt of his hand, brought the Yankee fighting aircraft back to an even keel, with a beautiful gliding movement."
