To Chester Bohn (Bell Telephone engineer), Chicago: “…I am still at the flying game as you can see and trying to [do] something unusual or something that the other fellows have not done…I wrote to Bill and tried to get him to enlist in my squadron and he was to tell you to join also before being drafted, and I never heard a word from either of you. However, Bill always was wild and careless so I did not feel bad about it.  Yes I was in the New York-Toronto Race. I won first prize $2,500 also the American Flying Club Trophy and the Government Reliability Race, but the only thing I got out of it was a gold watch. I have been doing some experimental work with a super-charged Liberty motor. I can maintain full H.P. up to 22,000 feet. I have been up to 37,000 feet with a passenger…I am sure I will be able to reach 40,000 true Altitude by myself before long. 31,800 feet is the world’s Record for height with a pass. I am in charge of all test experimental flying for the Government and have been for about a year and a half. They froze me out of the trans-continental race by not sending me a entry blank in time. I have a machine here that will make 152 m.p.h. and they were afraid of me, but just wait, I’ll get at ‘em yet…” After working as a chauffeur and a telephone employee, Rudolph William Schroeder became an airplane mechanic before enlisting as a pilot in the US Army Corps, soon breaking all records for “looping the loop” 39 times in his flying machine. The 34 year-old Major went on to win the One Man World Altitude Record in 1920 and later became an Aviation Engineer with his own aircraft development company in Illinois.
