3 brite lights running parallel to us, merged into 1 and continued course, then Vanished 2-3 min, durationI and my wife were driving to our home in the country, heading East from Monticello on County Rd 175N. We've drivin this route for six years and know the surrounding area well. I was riding in the passenger seat, looking out the window for nothing in particular. As I glanced up to see what planets were visible, I noticed 3 brite lights running parallel to us at about 500-1000ft high ( the height a Ultra-lite plane would fly ) and about 1/2 mile to my right. There was 1 large brite light, and 2 smaller less intense lights running a crude triangle formation. After what seemed a couple minutes all 3 lights merged together, and continued on as 1 brite light. At that point I stammered to my wife to pull over, she asked why, and I looked at her and told her what Id seen. She looked out the windsheild, and replyed she didnt see anything. I told her It was too the southeast and looked back out my side window. Being distracted for a couple seconds I lost site of the light, and never saw a trace of It the remaining way home. Like it vanished.........the event was 2-3 minutes...((NUFORC Note: Date is approximate. PD))
