Harnessing the Sky: Frederick "Trap" Trapnell, the U.S. Navy's Aviation Pioneer, 1923-1952

Harnessing the Sky: Frederick "Trap" Trapnell, the U.S. Navy's Aviation Pioneer, 1923-1952 by Frederick M. Trapnell Jr. and Dana Trapnell Tibbitts. Naval Institute Press, 2015, 288 pp.

In the vast literature of World War II airpower heroes, is it possible to have missed a vital aviation innovator? The biography of Frederick "Trap" Trapnell questions the notion that innovation relies on the inspirations of elite scientists and exploits of new technologies. Set in the pre- and post-World War II era, this biography illuminates the infancy of America's test pilot program. Notably, it is written by Trap's son Frederick Jr. and granddaughter Dana Trapnell Tibbitts. Although the authors' kinship clearly establishes credibility, the biography spends relatively little time on Trap's difficult home life, instead casting him in a predictably heroic light. Nonetheless, the familial bias does not diminish the captivating story of arguably the first engineer test pilot, who emerged during a time when that job at home was as dangerous as the war overseas.

Trap's ability to change tactics, procedures, and mind-sets during his lifetime is still a quality often taken for granted in today's Navy and Air Force. To name a few of his accomplishments, he was a superior pilot, commanded an aircraft carrier, invented the antispin parachute, and survived two bailouts and a crash landing. However, in arguably his innovation of greatest impact, Trap developed the balanced design philosophy. While others chose to sacrifice safety in the pursuit of performance, Trap's procedures mitigated often-unforeseen dangers, resulting in superior aircraft for the Navy. Deviating from precedent, he built engineering teams that not only isolated aircraft design flaws and vulnerabilities but also proposed concrete fixes. This scientific approach to improving the force birthed the engineer test pilot and revolutionized naval flight-testing. In a time when Hitler's Germany was rolling through Europe and when Japanese technology was on par with America's, Trap's innovations, which extended into every facet of aviation, were critical to wartime success.

Trap's innovations succeeded because of his emphasis on changing practices instead of acquiring new technology. However, he was not the only innovator of the time: Airmen such as Billy Mitchell also made procedural advancements--albeit through more blustery processes. In contrast to Mitchell and other pilots who gained fame from speed records, daring raids, and even public trials, Trap remained the quiet professional. Highlighting this humility--and in contrast to Jimmy Doolittle's 574-page autobiography--the authors showcase Trap's use of only two paragraphs to summarize his career. Even so, his quiet efforts were pivotal in designing and testing aircraft in the twentieth century through his methodology of integrating flight-test pilots with aircraft developers.

A comparison of Trap to other naval innovators, such as William Moffett, reveals that he had considerably less involvement with the political battles that surrounded naval aircraft. However, in an action that restored naval aviation's credibility, Trapnell was one of the first to recognize US aircraft's limitations against their World War II German and Japanese opponents. To resolve this dilemma, he personally redesigned the Navy's test aircraft--the F4F Corsair--ensuring it could outfly the Japanese Zero. Importantly, Trap found a key balance, showcasing procedural innovation without neglecting technology. His focus on changing mind-sets and procedures combined naturally with technological advancements to create one of the most successful naval aircraft of World War II.

For the astute listener, Trap's call for advancements in tactics, procedures, and mind-sets can still be heard. His lessons were drawn at a time when, much like today, senior leaders requested that aviators turn their efforts toward airpower advancement. Benchmarking a humble approach to innovation--often lacking in today's technology-dependent forces--Trap demonstrated that the definition of improvement does not need to be inextricably linked with high-end contracts. Instead, his message is that innovation has to do with improving cultural standards and war-fighting processes; technology is simply one means of arriving there.

Harnessing the Sky is a valuable read for contractors and flight-test engineers. However, it is also applicable for aviators who are challenged to innovate in a technology-dependent force. For any audience, Vice Admiral Trapnell is worthy to stand among both the pioneers of military aviation and today's flight-test programs. His legacy prompts military operators to question the conventional thinking that ties innovation solely to costly new technology. It is of key importance that aviators--like Trap--find the procedures within their purview that they can refine to meet current threats. The principal message of Fredrick Trapnell's example, given a clear voice in this inspiring biography, is that all United States flyers need to be innovators.
