U.S. Air Force Analysis of Flying Objects in the United States, 1-100

Mrs Hedstrom was the first to notice an object traveling at a terrific speed in a northeasterly direction. While discussing this with her husband and a neighbor all three saw ten similar objects proceed rapidly in the same direction in the form of a triangle. As they were disappearing 3 objects peeled off the left flank and proceeded in a more northerly direction. The remaining objects closed ranks and proceeded on a [redacted] NE course. Five minutes later another group of 3 objects were seen proceeding in the same direction in triangular formation. Three to five minutes later another triangular formation of five or six objects was observed going in the same direction. Then a few minutes later the three witnesses saw 35 to 50 flying in a triangular formation still in the same direction. Approximately 20 to 25 minutes later similar objects were noted coming back over the city in a southwesterly direction. Generally they were in groups of 3, 5 and 7 and followed each other at approximately 5-minute intervals. Detective Frazier and Mr. Hedstrom did not think they were meteors as (1) they flew on a level line and did not appear to drop (2) Observed triangular formation They did not think they were birds as: (1) They were lighted from the inside. Were not the reflection of city lights since: (1) They observed triangular formation and changed course from NE to SW direction. (2) Observed to close ranks and form a triangle again.
