Officer McDowell stated that at approximately 1305, 4 July 1947 while he was on duty at Prescinct #1 and feeding the pigeons in the parking lot back of the station he noticed that the pigeons became quite excited over something and fluttered in the air. Officer McDowell in looking around to see what had disturbed them saw 5 large discs in the air east of Portland; two discs flying south and three flying in an easterly direction. He stated he could determine no color to the discs but advised they were dipping in en up and down oscillating motion and were traveling at great speed. He was unable to give an estimate of the speed or altitude of the discs they were out of sight before any detailed observation could be made. Officer McDowell revised that he notified the Police Radio who immediately broadcast an alert. He saw no indication of any motivating force nor heard any sound coming from the discs and could give no description other than round.
