Read from the scan by GLM-OCR; expect the odd misread word.

6. Is operational preparation been observed to extend the range or ground cluster by this minor altitude, and did this condition exist during or near the time that unknown target was observed?
I
6. What effects of rain storms and lightning have been observed on this rain?
I
7. Are any checks made to determine if unknown target could have been one of our own aircraft? Yes. Aircraft were directed to the target by the controller. Target was believed to be another jet aircraft until observed by the flight leader.
8. Was any interception attempted? If so, give details. Intercept was successful, but target was too high for the aircraft to get close for positive identification. Pictures were taken.

III. SPECIFIC TARGET QUESTIONS
1. What technical personnel observed the unknown target? Have they been questioned thoroughly? What was their opinion? Maj. Smith, Flight Leader and Lt. Lott, Controller were observers. The target intercepted was not the target on the FPI. So it must have been flying the same course at the same time.
2. Was a permanent record "track" made of the target positions as they appeared on the indicators? If so, attach to this report.
None
3. At what range, altitude, altitude, and time was the target observed? Range 25 miles, altitude 230°, altitude unknown. High beam was used - target was above 10,000 feet.
4. How did the target appear in size and shape as compared with conventional aircraft targets? Normal
5. Was the target of consistent size, or did it change rapidly? Yes, until about one minute after intercept.
6. Was the speed of the target constant or variable? Explain. Speed consistent about 400 knots.
7. Did the target appear "fuzzy" or clear and sharp as compared with a known aircraft target? Clear until fade.
8. What other (aircraft) targets were observed in the same general area, altitude, and time as that of the unknown target?2 F-86's from 97th Fighter Interceptor Squadron, Wright-Patterson AFB, Dayton, Ohio, at 30,000 feet, M.S.L.
