At daybreak, object (with recessed light in nose, and soundless) passed by us in the low clouds. It was barely getting light enough to focus in on it. At its closest point to us, the light went off as it went into the low cloud cover. I was able to determine that from its nose the geometry was delta, or triangular, as I couldn't distinguish the shape of the rear half of the object. It was soundless, and there was no wind noises after it passed.

Myself and 2 close friends were in our cornstalk blind duck hunting one fall morning.  Our decoys were out, and it was still dark.  Daybreak was upon us, and as it got lighter, my vision of the distance increased. In those days, because of my extremely accute long distance vision, I was the spotter, and my 2 buddies manned the duck calls. The cloud ceiling was very low, as we looked to the East where the faint light of daybreak was commencing. Then about a quarter mile towards the Northeast, I saw a round light skimming in and out of view in the low clouds heading South at about 50(?) mph.  Because of the subdued lighting, identification was impossible.  However, when the craft passed directly in front of us at its closest distance (1/8th mile), my focus zeroed in.  Its light then went out as it went into the clouds.  I was able to determine that its light was recessed somewhat into the nose of the craft, and about a foot in diameter.  I saw only the first 10 feet or so of the craft.  Moving back from the recessed headlight, the shape was "delta/triangular".  My 2 buddies and I looked at each other in disbelief as the craft made no propulsion noises, or any wind-cutting noise in its wake.
