This lot of four books were used by Delphine Bohn during her training as a WWII pilot - she was one of the original 25 female pilots in the Women's Auxiliary Ferrying Squadron (WAFS), later known as the Women Airforce Service Pilots (WASP). Each book is signed by Bohn, sometimes multiple times. They come in a plastic bag with a note from the previous owner explaining how they came into his possession.
From the cafriseabove site:
On October 21, 1942, Bohn was accepted in the United States Women’s Auxiliary Ferrying Squadron (WAFS) as one of the original pilots. Her first training assignments were in Delaware and Big Spring, Texas. After completion of training, in April 1943, Bohn was based at Love Field, Dallas, Texas with the 5th Ferrying Group until deactivation on January 22, 1945. While with the WASP, she completed transitional training on BT-13, AT-6, PT-18, AT-9, G-78, AT-11, A-24, C-47, B-17, A-20, A-26, B-26, and P-38 aircraft. Bohn also commanded the 601st Squadron of the Women Airforce Service Pilots (WASP).
Three of the books are 7.25"x9.5" softcovers from a series published by the U. S. Navy's Bureau of Aeronautics Training Division in 1943:
1. Arctic Sense (29 pages)
2. Aleutian Sense (31 pages)
3. Patrol Sense (22 pages)
The fourth book is "Living Off the Land," a 79 page, 7.75"x9.5" softcover issued by the Army Air Forces School of Applied Tactics. There's no publication date. Like the other three, no author is credited.
The books are in good condition. Several have bent corners, small spots and indentations to the cover. Patrol Sense is stained on the back cover.
