Two army officers reported to Office, Director of Intelligence, Hq. Alaska Dept., Pt Richardson, Alaska, saying that they had witnessed an object passing thru the air at tremendous speed. Object appeared to be a sphere and did not give the impression of being sucer-like or comparable to a disk. Altho, the first officer stated that it would be impossible to give minute details, the object appeared to be 2 to 3 feet in diameter and did not leave any vapor trail in the sky. He stated the object appeared metallic and silver in color (like that of air lanes) As there was scattered cloud formations at 10,000 ft and the object was noted to be traveling below the cloud formation they were able to determine the approximate altitude. To the second officer the object appeared approximately 10 ft in diameter and compared it to half the size of a full moon on an ordinary night. He estimated the altitude to be only 3,000 or 4,000 ft. The object appeared broadside to the second officer and gave no evidence of a spinning motion or did he note a reflection. To him it appeared to be a dull metal finish. In conclusion the second officer pointed out that the object was definitely traveling against the wind.
