enroute to his office and before entering heard one of the local aircraft in the traffic pattern. Looking up he observed the aircraft and slightly to the left he saw 2 silver objects of either spherical or disco-like shape moving about 300 MPH at approximately 8000 ft heading about 320$ ^o $ due north. He immediately called S/Sgt Gerald E. Hammam, T/Sgt Joseph Ruvolo and Miss Jannette Marie Scotte. Witnesses all verified the sighting and the direction of the objects - all three stated that the objects were moving toward Nojave, Galif. Witness was sure it was not an optical illusion or that the objects were not weather balloons since they traveled against prevailing wind and since the speed at which they traveled and the horizontal direction taken indicated that they were not weather balloons. Furthermore they could not remain at the same altitude so consistently if they were weather balloons. Witness them attempted to get personnel (medical officers) to further verify the sighting but by the time the additional personnel had arrived at the some the original objects had disappeared due to the speed at which they were travelling. However, two of them sighted a third object of a silver spherical or disc-like nature at approximately 6000 ft traveling in circles over the north end of the airfield. Five out of the seven personnel saw this object All looked away from the object several times to make sure there was no eye strain. He stated that this object performed too tight a circle to be any type of known aircraft. Evaluation: Confirmed by other sources. Witnesses: S/Sgt Gerald R. Neumann T/Sgt Joseph Rurvolo Miss Jannette Marie Scotte
