Mr. Archibald adds another title to his increasing list of action-packed stories for boys. In this case, he has probed and explored all the techniques of windmill- helicopter- flying in the Air Force. Lieutenant Walt Sprague rebelled against being dog-tagged as Old Thunderhead's son. General Sprague explodes in rage when his son leaves jets to fly the unglorified 'copters. Mr. Archibald keeps a steady telescopic lens on Walt, and the story of the boy's struggles, his efforts to please himself and his father, moves at ripping speed. Boys will go for the amount of technical details about flying which are woven into the plot. The author writes in a more natural manner when he sticks to pilots and planes than when he describes the boy-meets-girl situation. However, he gives so little time to Walt's romance, that it does not detract from the exciting story. Not deep, but a solid, sound story.
