This collection includes information generated by the students and Butler staff participating in the Air Force ROTC program. There is a special emphasis on Angel Flight, an honorary organization of college women who promote the interests of the Air Force and Air Force ROTC (Reserve Officers Training Corps). The collection includes a pledge manual, photographs, and ephemera. While the bulk of the textual materials come from the 1980s, the photographs document Butler Air Force ROTC events from the 1940s to the 1980s. Many photographs have writing on the back, identifying the people and/or events.
