Used with permission of the publisher, W. In the years following the Wright brothers’ 1903 takeoff, aircraft were designed via what a NASA history calls “an intuitive, daring empirical engineering loosely connected at best with any theory of aerodynamics or structural integrity.” Plane makers had some ideas about how to mimic flight while on the ground, but these were crude approximations with little sense of similarity or workability (that measure of practicality and reproducibility). The assessment of a plane as insufficiently robust was frequently made amid crashing noises and roaring flames.

In the 1920s, the life expectancy of a pilot for the U.S. Air Mail Service (among the first practical uses of civilian aviation) was four years, and the service lost 31 of its first 40 pilots to crashes in its first decade. Much of the problem was that human flight was so new, nobody could fully answer the first, fundamental question in the testing litany: What will the product face, and how might it fail?

Happily for pilots and passengers since, the U.S. Army let one Jimmy Doolittle pause his work as a test pilot to help figure it out. Thanks to a cringeworthy script and a hammy portrayal by Alec Baldwin, anyone who saw 2001’s Pearl Harbor may think of Doolittle as a jingoistic flyboy who spouted lines like “Victory belongs to those who believe in it the most and believe in it the longest ….

We’re gonna make America believe.” The real Doolittle was, in fact, not just a daring and gifted pilot but an inveterate mischief-maker and premier aeronautical mind who worked to rationalize the airplane into something that could be known, predicted, and judged. Something that could be tested. Small but fierce, Doolittle was a champion boxer in college, an avid acrobat (he was particularly keen on tumbling), and one of the many people who took to flying in the early years of the 20th century.

He started as a teenager building his own gliders from sticks and cloth, promptly crashing each one. In one case, he tied himself to his friend’s car to pick up speed for takeoff, only to end up being dragged down the road. His autobiography, _I Could Never Be So Lucky Again_ (1991), includes an inordinate number of stories that end with him climbing out of a wrecked plane, amazingly unhurt, then being chewed out by a superior officer.
