This really should have ended as a day dream, for any little boy interested in airplanes would accept the story as something in his wishing world, but question it as really happening to Bobby. Bobby wants to be high and the stilts his grandfather gives him, the windmill he climbs seem inadequate. So they go off in a two-seater, but that isn't enough. They switch to a hydroplane. Then to a helicopter. Then to a fire-fighters plane, and from this they parachute down to fight a fire they have spotted. Then a clipper And even then Bobby has aspirations beyond these for the sort of plane he wants. And begins to save his money to buy one. As a dream it might go over. Told as a story- it has too much for small readers.
