Report on Airplane Camouflage, Tests of October 1, 1936, on Reduction of Daytime Visibility of Airplane by Artificial Illumination
Abstract
Twelve 420 watt lamps were mounted under the lower surface of the fuselage of an airplane. During three daytime flights of the plane observers on the ground concluded that at distances up to about 2 miles the lights illuminated from one-fourth to one-half of the under surface of the fuselage to a brightness slightly less than that of a cloudy background and somewhat greater than that of a blue sky background. At distances from about 3 to 6 miles, when viewed with the unaided eye, neither the lights nor any effect of their illumination were perceptible.
