As the resonant wave moves around the glass, it drags the water molecules with it, creating a wave of water that you can see near the edge of the glass. You can see that in its response to Mike Pero’s offer to get a charter plane up to Erebus. The Quartermaster Corps, responsible for the design and supply of all authorized insignia, resisted further designs for the AAF until 28 July 1945, when command arcs (arc-shaped tabs, see example above in Command structure) were authorized for wear above the AAF insignia by members of the various support commands. This sleeve insignia, which consisted of a blue triskelion superimposed on a gold circle, was retained after GHQ Air Force became Air Force Combat Command on 20 June 1941. The triskelion represented a stylized propeller that symbolized the three combat wings of GHQ Air Force. Female service dress went through an evolution of patterns over the course of the war years, however throughout the period the service uniforms both summer and winter generally consisted of the WAC pattern hat or women’s garrison cap, suit coat (winter only for enlisted women), shirtwaist, four-in-hand tie, skirt, russet leather women’s service shoes and hand bag.

The ANC summer service uniform consisted of a similar suit in beige with maroon shoulder strap piping and cuff braid, beige ANC cap or beige garrison cap with maroon piping, white shirt, and black four-in-hand tie. During World War II the first flight nurses uniform consisted of a blue wool battle dress jacket, blue wool trousers and a blue wool men’s style maroon piped garrison cap. The women’s olive drab wool “Ike jacket” was also worn as were women’s service trousers. Most jackets featured a Mouton fur or shearling collar, but a popular variation known as the “tanker jacket” had a wool knit collar that was less confining. Made of seal brown horsehide leather (later supplemented by goatskin) with a beige spun silk lining (cotton after 1939), the jackets featured an officer’s stand-up collar, shoulder straps, knit waistbands and cuffs, a zipper closing, and unit insignia. In early 1943 the AAF did not renew its contracts for leather flight garments and began production of flight jackets and flying trousers made of cotton twill and nylon blends with alpaca pile linings.

Sage green fatigue uniforms of herringbone cotton twill for women, along with women’s combat boots, field jackets and flight clothing, were manufactured by the U.S. The AAF standardized the sage green or light olive drab B-10 flight jacket on 22 July 1943, accompanied by matching A-9 flying trousers with built-in suspenders, and the combination became widespread in the Eighth Air Force by early 1944. The heavier B-15 jacket followed at the end of the year, with the A-11 trousers issued in the last months of the war. The uniform was worn with either the ANC light blue or white shirt and black tie. Nurses attached to the AAF wore Army hospital whites, or prior to 1943, the ANC winter service uniform consisting of the ANC pattern dark blue cap or garrison cap with maroon piping, suit jacket with maroon cuff braid and gold army buttons, light blue or white shirt, black tie and light blue skirt, shoes were black or white. According to General Order 18 Hq ETOUSA the patch was to be worn by personnel of the Army Air Forces who held currently effective aeronautical ratings or who were authorized to wear the aviation badge for air crew members, during the time such personnel were currently assigned to combat flight duty.

The off duty dress was a separate ANC pattern in olive drab shade 51 or beige. The new olive drab ANC uniforms were the same as those for WAC officers except for the ANC pattern hat and the ANC pattern handbag. After 1943 the ANC adopted olive drab service uniforms similar to the newly formed WAC. The colors essentially mirrored those of their male counterparts of corresponding rank in the equivalent service uniform although fabrics differed. Female USAAF uniforms were either the uniform of the Army Nurse Corps (ANC) or that of the Women’s Auxiliary Army Corps (WAAC) with appropriate USAAF branch insignia. In the summer of 1943 the Women’s Army Corps (WAC) replaced the WAAC. Although female auxiliary organizations such as the WAAC, Women’s Auxiliary Ferrying Squadron (WAFS) and Women Airforce Service Pilots (WASP) performed valuable service to the AAF, only the ANC and the WAC were official members of the U.S.
