(USE REVERSE SIDE OF SHEET IF MORE SPACE IS REQUIRED) Has anomalous propagation been observed to extend the range of grourid clutter by this radar at this site, and did this condition exist during or near the time that unknown target was observed? Condition was not apparent at time of sighting. What effects of rain storms and lightning have been observed on this radar? None Were any checks made to determine if unknown target could have been one of our own aircraft? Yes, Negative Results. Was any interception attempted? If so, give details. No Was a visual and/or Auditory observation made simultaneously with scope observation? If so, give detailed description, Yes (See AF Form 112, IR-1-53W, 34th ADD - forwarded) III. SPECIFIC TARGET QUESTIONS ¢ Did any technical personnel observe the unknown target on the Radar Scope? Have they been questioned thoroughly? What was their opinion? No Was a permanent record "track" made of the target positions as they appeared on the indicators? If so, attach to this report. (Plot on back of page 1.) No At what range, azimuth, altitude, and time was the target observed? Range: 9 miles; Azimuth: 270°; Alt: 10 to 15,000 ft. (estimated) Time: 2115 MST, (26 Jan 53). How did the target appear in size and shape as compared with conventional aircraft targets? Much larger and moch brighter on scope. Was the target of consistent size, or did it change rapidly? Consistent size at all time on scope. Was the speed of the target constant or variable? Explain. Variable, 12 to 15 MPH, Did the target appear "fuzzy" or clear and sharp as compared with a known aircraft target? "Pazzy" What other (aircraft) targets were observed in the same general area, altitude, and time as that of the unknown target?
