TIHE DEVELOPMENT OF THE AIRPLANE ENGINE WAS LARGELY DUE TO AUTOMOBILE RACING Of the hundred thousand people who witness automobile races such as the Indianapolis Speedway Classic, pictured above, how many realize that the airplane substantially owes its development to the keen rivalry which exists between the builders ofautomobile engines? Such competi tion on the track resulted in the improvement of the gasoline engine to the point where its adaptationfor aircraft usewas quickly possible and eminently successful. These great speed and endurance tests have been directly responsible for savingmany lives, forweak spots and faulty con struction are inevitably exposed during the long grind of the race, and as rapidly as these defects aredetected they areeliminated from alltypes of cars by automotive engineers. Thus touring accidents, caused by the breaking of steering knuckles,tie rods, axles, etc., areminimized and tragedies of the highway caused by mechanical shortcomings are constantly becoming less frequent.
