Captain Joseph Mackey’s airplane was flying over the ocean on its way to Great Britain when engine trouble started. He turned back and made a crash-landing at night in the deep snow of Newfoundland. All the men in the plane were killed except Captain Mackey, who was badly hurt.
    Captain Mackey waited all the next morning for an airplane to come in search of him. In the afternoon he set out to find help. He went about a mile but found that he was too weak to go on through the snow. Half walking and half crawling, he made his way back to the plane.
    The second day many planes passed above him, but none of the pilots saw him. The third day Captain Mackey heard a plane coming nearer and nearer, flying very slowly. It flew right over him and passed on. Then he gave up hope of being found. In a few minutes the plane returned, and pilot dipped one wing to get a clearer view.
    The pilot came down closer for a better look, and then he saw Captain Mackey waving his arms. The pilot quickly climbed higher and sent a radio message. In a short time a plane came and dropped a sleeping bag, food, medicine, and tools for Captain Mackey.
