Summary : Winter of 61-62 or 62-63; large illuminated white lite with several small blue lites converging to and then dimming and leaving almost straight up at tremendous speed. Local radio station flooded with calls Would like to know why never heard about since???I was driving semi at the time and approaching Williston from the east after dark.Since this happened about 35 years ago I dont recall the date or time, but do know what I saw. I watched what I first thought to be a farm yard lite until I realized it was moving. When it appeared to be over Williston is when it flared up as stated previously and the smaller blue lites; coming from different directions converged on it. Just curious???
