In 1958 living in hostel, 19 year old males sharing a bedroom with one other male. Early in the summer morning, it seemed quite light outside but not really dawnlight.
I was awoken by my room mate, the room was small and narrow, he slept at one end and I at the other, we were on the first floor up, the hostel being on the outskirts of a small village, our room had a large, long window which looked out above a small conservatory, flat roof, and over the large lawn, then into the middle distance of field and hill, then skyline.
My room mate woke me from sleep, saying:
What's that out there?
I eventually got up and went to the window, his view from his bed was to the left of where I stood, so I looked in that direction, I did not see anything, but I instinctively looked up to my right and there, above a leafy chestnut tree, it seemed just a few feet above, against the clear sky, was this saucer shaped object.
In the 1950s I, we, did not know anything about flying saucers or UFOs, and indeed I had completely forgotten about the incident when wakenig up in the morning proper. The size of the saucer was, or seemed, about 4' in diameter and about 3' in height. It was completely silent,
I did not know what it was, it had, on the raised bulb shape on top, or I'm not sure now, whether it was lower down on the main body, a horizontal row of oval like windows. Frosted as I coud not see into them.
I looked really hard into the windows and at that moment it just shot away, totally silent, no lights and in a blinking of an eyelid it had gone.
Oddly, I puzzled over at the time concerning the distance and speed which it became so small, to a pin prick of white light, then gone into the middle distance yet against the background of the hill, so it did not seem to go high and away in the sky but more of a trajectory curve, that's my adult word knowledge.
Years later I thought that my peering into the windows was an energy interference and so it made off. The saucer had a short stream of red behind it which seemed to be a connected to it, till the saucer had pinpricked into a tiny white light.
I wondered why it, seemingly, had moved from left to right outside the window, only about 80' up in the air, and our window was say 20' up and I wondered and felt sad that if I had not of eagerly peered into its windows whther it would have stayed longer.
Apart from another friend coming up to me the next day, saying that my room mate had seen this object in the sky, I had completely forgotten about it and then, I had never had it in mind until 25 years later when my young son was all into UFOs, 1980s, that the memory suddenly shot into my mind, fresh again and since then it has been in and out of my thoughts.
This place was in a Hertfordshire village, Waterford, in England, United Kingdom.
Incidentally, and a big coincidence, in early 2002 I went to visit a friend up in the north of England, Newcastle, and he introduced me to a female friend of his and as she and I chatted we discovered that in the 1950s she had lived in the same, Waterford, village and at the same time. I told her of my saucer sighting, surpringly she and her family had, often, seen lights over the common.
