Subjects flying in a light aircraft at 3000-ft altitude estimated the locations of ground targets in relation to two fixed markers. Sighting was done with naked eyes or by use of a special sighting device. The estimates were expressed in polar coordinates the distance was expressed as a ratio to the inter-marker distance, and the angle in terms of clock hours with respect to a line through the markers. A target precisely in middle between the markers produced no error. Otherwise, errors--the distance between the target and its estimate--increased with greater target-to-center distances. The sighting device failed to produce any improvements, due to the amount of tracking necessary and to turbulence. Author
