A book for boys who like things clear cut. Jim Warren is the good guy-- all good. He does his homework, has a job in his father's grocery store, helps his mother with the housework, and builds files model planes. Jim's father is the villain, with no time for his son. Jim's friends are courteous, kind, helpful and friendly, and they all fly places. Jim wins a trophy flying his plane; his father sees the error of his ways, and all ends happily. The characters are dull, the plot almost non-existent.
