white,small,quiet,smooth,cigar shaped but pointy on both ends.my friend and I were traveling north down Mesa rd. when we saw a white object that looked like a cigar but with both ends pointy insted of rounded. This object travled from east to west down the middle of the valley. It was at about 500 ft. and just glided silentle by. It had no wings, tail, exaust, etc. It was only about the size of a jet fighter and was traveling at about the same speed those planes cruz at.It was also very smooth looking.((NUFORC Note: Please see preceding report from Alameda, CA.
