i was on the outside stairwell of the motel 6 in west hollywood. me and my friend nick were smoking a cigarette and over the brim of my hat while looking at the stars came a yellowish disk. after about 10 seconds of this disk moving NE to SW in a straight line it rotated 90 degrees, while still moving in the same direction. then the yellow light stopped and the back of the craft had many little lights changing in luminosity and color. only saw it for about 30 seconds before it disappeared behind the buildings heading toward venice beach. this craft made no sound what so ever and flew under 500 feet above the city. an hour later i went outside again and noticed a triangular arrow shaped stealth plane or drone with no lights flying over the same area.
