1978 UFO report from Strong, ME

A report was filed April 12th on the MUFON website (http://mufon.com/) relating a 1978 sighting (reproduced verbatim below):

Three of us, July 1978, teenagers at the time, were night fishing for eel on the shore of the Sandy River in Strong Maine. We heard a whooshing sound, like the wind, directly overhead, we looked up, and said at the same time, "Wow look at that", and there was a black triangle, with rounded points. Each point had a fixed colored light, (not blinking)red, blue, and green. The round lights were at least 10 feet in diameter, much bigger than any man made aircraft lights i've seen otherwise. The triangle was an estimated 300 feet each side. The craft was approximately 300 to 400 feet above us and made no noise except the sound of the craft cutting the air. The speed of the craft was about 20 miles per hour, too slow to be a conventional aircraft. It was below stall speed and should have crashed, but it kept slowly flying west, up river until it went out of sight. Time span was about 30 seconds. my brother still thinks to this day that it was an experimental military aircraft. In my opinion, it was a technology out of our reach and beyond our capabilities at the time. This is the only flying triangle I have seen. I have had 9 other experiences that I will share at another time, 4 of which were during my childhood in the 1970s. Keep looking skyward my friends. Phil62.

Just one more example of the high-strangeness era of the 1970s! Even Maine wasn't immune to a rash of UFO sightings. In the September 7, 1976, issue of the Biddeford Journal, mixed in with all the other classified ads for lost wallets and "Hairdressing in your home" by Mr. Andre, the following ad was run:

PLEASE report UFO sightings or encounters in your area to:
Shirley C. Fickett, 797-2664, International UFO Bureau, East Coast Headquarters, 482 Auburn St., Portland Me. 04103.
