Berlin, July 11, 1938
 
Dear Mr. President:
 
 During the last few weeks I have had a number of
talks with the Military Attache, and especially with
the Air Attache, concerning German air production.
I have also had talks with Mr. Glen Martin, Mr. J. H.
Kindelberger and other American manufacturers and
experts.
 
 The conclusions reached from these talks are
startling to any one used to thinking that France,
England and the United States, especially the United
States, held at least a small margin of superiority
in the air over Germany. The facts are that Germany
in the short time since throwing off the restrictions
applicable to production of military aircraft, has
produced an air arm second to none in numbers and
quality of first line fighting airplanes. The
