## CONFIDENTIAL ## REMARKS Statement given by Major J. C. Wise, Test Pilot, Muroc Army Air Field, Muroc, California. On 7 July 1947, at approximately 10:10, while running up the XP-84 on the ground I noticed everyone was looking up into the air. Off to the north about 10,000 to 12,000 feet altitude, was an object that I assumed at first to be a weather balloon, but after looking at it for a while I noticed that it was oscillating in a forward whirling movement without losing altitude. It was traveling about 200 to 225 MPH, and heading from west to east. The object was yellowish white in color and I would estimate that it was a sphere about 5 to 10 feet in diameter.
