What did the naval-aviation thesis argue?

What was the argument of the PhD thesis?

It argued that historians undervalue observers in the development of naval-aviation strategy and tactics, and engineers in the development of aircraft.

The thesis concerns the development of naval aviation in the 1920s and 1930s. Its argument is that observers receive too little credit for their role in developing strategy and tactics. Engineers are likewise undervalued in accounts of aircraft development. These are related questions about which participants receive attention in histories of naval aviation.
