Small white glowing orbs, dark objects, floated, noislessOn March 30 and 31 of 2012 at 10:10 pm me and 5 others saw several small objects that we would not identify. This event happened near the fire station in North Bismarck. There is a small park in the area that you could probably see them at. In the sky they first appeared to be flying in a formation. And later by themselves seemingly on a schedule. I saw the formation at about 10:10 pm the first night. I ran to get my family about ten minutes later we saw a single object it looked like a 3D triangle that you could see through with glowing orbs on each tip. This one had about six orbs. They were very dim and were glowing from within. The orbs were connected by skinny bars of blackness. The objects were hard to see because they were mostly darkness except for the orbs. This craft seemed to rotate as it floated across the sky. It made no noise whatsoever.A few minutes later we saw another with only about 3 points of light and later another with two it looked like a dumbbell shape with one orb on each side. We also saw one that was a single orb. The appearances lasted for an hour and the crafts seemed to be on a schedule one going this way one going another direction. All eventually moving over us at the same point. They seemed really small smaller than a car and close. Definitely under the cloud line. I know that because before they disappeared a dense fog moved in directly over us one appeared under the fog moved into it and they they were gone and the fog moved out. The same thing happened the next night. I looked for them that time to see if they would come again. I asked my dad to go back and look for them again since I don't live in ND anymore. Hopefully he can get some video and pictures. If I were to have any interpretation as to what they were it would be that they seemed like some sort of surveillance to me...
