A quest to understand the past has led to a prestigious international award for an Air Force Institute of Technology faculty member. Dr. Timothy Takahashi, Associate Professor of Aerospace Engineering, has been honored by the Royal Aeronautical Society with the "Best Paper" award for his groundbreaking work, “Ezra Kotcher: Father of Bell X-1 and X-2,” which uncovers the forgotten story of the man behind the plane that broke the sound barrier.

The journey began in the archives of AFIT’s D’Azzo Library, a repository of aeronautical history stretching back over a century. Dr. Takahashi and his students were combing through historical documents, seeking to understand the decision-making that separates successful military aircraft from failures.

"The D’Azzo Library at AFIT has been a remarkable treasure trove," Dr. Takahashi said. A pivotal moment came when AFIT librarian Ruth Randall pointed him toward a little-known collection of personal papers belonging to Colonel Ezra Kotcher, an early AFIT professor and Air Force officer.

What Dr. Takahashi found was a historical goldmine. Kotcher's meticulously curated notes and memoranda from the 1940s revealed a hidden story. "It became clear to me that he was the driving force behind the technical design of the Bell X-1 rocket plane," Dr. Takahashi stated. “Dr. Kotcher’s thinking process was very modern, linking math models to fit test data.”

His research revealed that Kotcher was the leader of the conceptual design team, personally sketching the concept vehicle and setting the technical requirements that would allow Chuck Yeager to pilot the X-1 past the sound barrier in 1947. Kotcher’s notes even detailed the political maneuvering required to get the revolutionary rocket plane built over the objections of those who favored a slower, jet-powered alternative.

Dr. Takahashi's resulting paper not only earned him an award but has rewritten a key chapter of aviation history. In recognition of this achievement, the D’Azzo Library is hosting a new display featuring the award and telling the story of Dr. Takahashi's discovery.
