Eglin Field issues report on day time camouflage, May 26, 1943

Report No. 3-43-30 was issued by Eglin Field on May 26,1943, titled "Test of Daytime Camouflage”. This covered tests which had been run to determine the effectiveness of blue and gray paints as camouflage against lateral observation. It was concluded that gray was a better camouflage for side surfaces rather than the standard dark olive drab.

The report recommended that gray should be used for the side surfaces of heavy bombardment and large transport aircraft, because the olive drab often became darker or lighter under tropical conditions and lost its camouflage value. Eglin Field suggested that Mat. Com. investigate the color change of olive drab.

Markings for walkways and “No Step” added to Spec. 98-24105-Q, June 7,1943.

Amendment No. 4 to Spec. 98-24105-Q, issued on June 7, 1943, added a new paragraph, E-19, which read as follows:

E-19. Marking for Walkways. – All walkways shall be differentiated from other external surfaces of the airplane by a border two inches wide in black. The surrounding areas immediately adjacent to the walkway shall be labeled “NO STEP”.

This was the first official use by the USAAF of this now common marking (note, though, that B-17s had used such markings from their first deliveries).
