โฆ Synopsis
THE object of the investigation described below was to analyze the various aspects of the visibility of airplanes, to ascertain the possibilities of attaining low visibility in various phases of airplane activities, to arrive at specific practical recommendations, and to eliminate guesswork by supplying a scientific foundation consisting of measurements for the solutions of the problems involved in obtaining low visibility. The war closed before some of the many interesting details could be thoroughly unraveled, but the fundamental data upon which the attainment of low visibility for airplanes may be founded, are presented in this paper . The work was conducted primarily for the Science and Research Division of the Bureau of Aircraft Production from whom permission for publication has been granted . The original reports contained a number of illustrations in color which will not be reproduced in this paper . Furthermore, it does not appear profitable to present all the details of the original discussions and recommendations .
