This is just something that happened and you may want to check it out. From June 1956-57-58-Aug.1959 we were stationed at Malstrom A.F.Base in Great Falls, Montana...I don't recall which year it was, but in the summer during a Baseball game at the local park.. 3 balls of light came down and bounced around on the feild and then suddenly "took off" Witnessed by hundreds of fans , it was big news in the news papers at the time. They said it was ball lightning, Didn't go over with the locals who were use to Northern Lights, etc. Just something you may want to check out. I can't find anything about it now.((NUFORC Note: We have spoken with this witness, and she seems quite credible to us. We have invited her to try to determine the date of the incident more precisely, and to obtain the newspaper article about the incident. PD))
