Lights would chase each other & change colors & sizes. Some would blink out & some would blink on. Brighter green light stayed low & stationary. Some of the red lights were very bright but would change to white or disappear. One small white light sped in from long distance to join with others. After about 10-15 minutes a jet came towards us from south & all lights immediately disappeared. Jet went through exactly where lights were & turned & went back the way it came. Lights did not reappear. My brother-in-law saw all this with me. There was never a sound from the lights & they were never more than 1/4 mile away.
