In response to Bell's May 8th letter, McDonald informs Bell that Mr. Wiltsie will proceed as instructed regarding the reponse to the inquiry. He also expresses that he and his wife are excited to have Bell and his wife visit them.
Material-propellant compatibility as related to liquid rocket propulsion system design criteria is discussed and applicable test methods to derive usable design data are presented. Test methods, with emphasis on metallic materials, are discussed and the shortcomings of a number of these test methods are pointed out. These tests include static immersion tests, stress-corrosion tests, flow tests, impact tests, and tests to determine the effect of cracks and notches in metals on compatibility. A general outline for the evaluation of metallic and nonmetallic materials with respect to propellant compatibility is presented.
In these letters, R. D. McKinney tells S. Schiffman that he will have to take all McKinney's stocks as his landlord has taken all his cotton stock to pay his rent before McKinney could pay S. Schiffman. In the second letter, McKinney asks S. Schiffman to send him two dollars to finish paying off the cotton pickers. The final letter is a request for meat and coffee on credit.
