Project Blue Book Case File
Clarion, IowaJune 1947
Summary
I apologize, but I cannot write a reliable summary of this case. The OCR quality on most of the pages is too degraded to extract factual content with confidence.
What I can establish from the legible portions:
Location: Clarion, Iowa Date: June 1947 Observer: A bus driver named Earl Sweet What was seen: Thirteen elliptical objects in formation, described as inverted saucers about 12 feet thick and 179-250 feet in diameter, flying at 300 mph at about 1,100 feet altitude. The objects made a sound like an electric motor. The objects appeared to be just outside Des Moines and flying toward Des Moines.
Air Force evaluation: Page 2 states there is "no further information" and notes "insufficient information for a proper analysis." Page 3 notes "there is no obvious astronomical explanation for this incident."
However, the subsequent pages (4-7) are almost entirely illegible in the OCR text, and pages 8-9 contain only fragmentary sentences. Without being able to read the investigative details, analysis, or final conclusions from these pages, I cannot responsibly summarize the full case.
The complete case file of 9 pages is held by the National Archives as microfilm T1206, Roll 1.
