NACA reports,, 1958.

The Melvin N. Gough collection spans from 1919 to 1971 and includes a wide variety of materials reflecting Gough's career as a test pilot, NACA administrator, and flight safety investigator. It is especially rich in materials from his years at Langley and equally rich on the topics of aviation safety and accident investigation procedures.

The papers are organized largely according to Gough's own filing system, and there is some degree of overlap in the contents of folders. Many of the folders include manuscript materials and other items such as magazine articles and newspaper clippings. The NACA reports and other documents that are individually listed include manuscript annotations, correspondence, or other items that make them unique. Documents published before 1930 are also listed individually, whether they have manuscript items associated with them or not. Other NACA reports and miscellaneous publications are arranged chronologically. NACA reports are usually grouped by year; other publications are grouped by decade.
