All objects appear to have the same characteristics in regards to shape, color, size and relative motion. 5 The shape of the objects appears to be oblate or disk shaped, color; blue-vhite, and maximum and minimum size; 90 and l6 feet. The size is based on the assumption that the objects are five miles from the observer. ''. 6. Fade in and fade out of the objects were analyzed as in 3 above. In this case the group movement was such that the distance between the objects and camera was increased so that the objects could not be recorded on the film thereby causing the apparent fade- out. Fade-in as attributed to a shortening of the distance from the fade-out area to the camera station. 7. Plots of the groups indicate that the objects move counter- clock-wise relative to the axis of flight path. However, nothing has been detected which indicates motion of the individual objects about their own axis although this motion appears to be likely. were made: axis, and In determining the velocity of the objects three assumptions a. The camera was held steady during Part III of the film. b. The object* were moving perpendicular to the optical c. The objects were five miles from the camera. It is obvious that (b) is a fallacy^ however, this assumption will give the minimum velocity and the actual velocity is greater than computed. The assumption that the objects are five miles from the ,| camera is an arbitrary one. However, based on the emulsion speed and focal length, an object 50 feet in diameter and five miles from the , camera will be recorded on the film with sufficient resolution to Identify major details of. the object. It is felt that if these objects were closer than five miles at the time of recording, details would appear on the film. Velocity is computed to be 3?30 mph for a shift of 1 am per frame if the object is five miles from the observer.
