-walking with friends-seen it slowly fly above us(we were in a forest), and then it quickly flew awaysmall yellow lights around 4 big lights, purple, red, blue, white. the four lights in the middle were in a donut shape cut into 4 pieces. There were 2 tiny lights in the middle flashing. When it was leaving it went so fast we couldn't see it. When it was hovering it made a buzz humming sound, but we couldn't hear it when it flew away.
