A large, dark cigar shaped craft w/ lights

My son and I were returning home from an evening walk when we saw a very large UFO moving very slowly just above the tree line along a small mountain ridge at Temple Valley on the Windward side of Oahu. It was in the early evening & it was just light enough to see it; we had climbed the ridge before & found an old WWII lookout bunker up there; on the other side is a rural coastal road & a bay; it was a dark shade of no color,quiet, w/lights around its perimeter; seemingly defying gravity; I did not report it in fear of being labelled a "kook"; however, the next day sightings were reported on the other side of the island on TV news. We lived there for 20 years & that was the only time I heard of actual sighting. I now believe in ufo's, although I suppose our military could have been testing something new, but is was definitely not a plane; from our view it looked like a giant cigar in the sky.
Date is approximate.  PD
