night flying: forbidding pilots with less than two years' experience from being scheduled except under clear conditions, prohibiting takeoffs in inclement weather, and requiring fully functional instruments and radio to continue on in poor conditions. Control officers on the ground were made responsible for enforcement of the restrictions in their areas. Suspension of the operation On March 8 and 9, 1934, four more pilots died in crashes, totaling ten fatalities in less than one million miles of flying the mail. (Ironically, the crash of an American Airlines airliner on March 9, also killing four, went virtually unnoticed in the press.) Rickenbacker was quoted as calling the program "legalized murder", which became a catchphrase for criticism of the Roosevelt administration's handling of the crisis. Aviation icon and former air mail pilot Charles A. Lindbergh stated in a telegram to Secretary of War Dern that using the Air Corps to carry mail was "unwarranted and contrary to American principles." Even though both had close ties to the airline industry, their criticisms seriously stung the Roosevelt Administration. On March 10, President Roosevelt called Foulois and Army Chief of Staff General Douglas MacArthur to the White House, asking them to fly only in completely safe conditions. Foulois replied that to ensure complete safety the Air Corps would have to end the flights, and Roosevelt suspended airmail service on March 11, 1934. Foulois wrote in his autobiography that he and MacArthur incurred "the worst tongue-lashing I ever received in all my military service". Norman E. Borden, in Air Mail Emergency of 1934, wrote: "To lessen the attacks on Roosevelt and Farley, Democratic leaders in both houses of Congress and Post Office officials placed the blame for all that had gone wrong on the shoulders of Foulois." Other supporters of the president outside of the government muted criticism of the administration by focusing on and excoriating Lindbergh, who had also made headlines by publicly protesting the cancellation of the contracts two days after they were announced, "as if his telegram had caused the deaths." Despite an 11th fatality from a training crash in Wyoming on March 17, the Army resumed the program again on March 19, 1934, in better weather, using only nine routes, limited schedules, and hurried improvements in instrument flying. The O-38E, which had been involved in two fatal accidents at Cheyenne, Wyoming, was withdrawn completely from the operation despite its enclosed cockpit because
