(Bahamas) Andros Island circle lasted 30 sec Metallic color no lightsI used to work on a navy facility called AUTEC Atlantic Underwater Testing Evaluation center........ Working for a company called Raytheon.........I was walking the beach like I do everyday after work or when I"m off. The day that this event happen was on my day off. Anyway I was walking the beach looking for old bottles that wash up. I heard a coastguard helo flying close by and I looked up to watch it. The helo was flying North and I was south, as the helo fly's past me I continue to watch it and then I see this object fly from from the West to East About 500ft off the deck. Then it stops over the Island across from me for not even a sec and then shrinks down to a bird size and then just vanishes on perfectly clear spring day. The object was metallic color with no lights,and was silent and moved very very fast.((NUFORC Note: We spoke via telephone with this witness, and he sounds to us to be sincere and sober-minded.
