Footnote 1: See, Daniels to Sims, 22 June 1917, DNA, RG45, Entry 517B. In this cable, Daniel’s requested “definite indications of what assistance in air work it desired the United States Navy to supply.”

Footnote 2: First used by the British in 1917, kite balloons (sausage-shaped and filled with hydrogen) were developed as a means of combating the U-Boat menace. Towed by destroyers with a crew member aloft, the balloons provided an excellent vantage point to spot submarines and surface raiders, as well as friendly ships. Still, Victory at Sea, 465.
