On 10/21/12 while at the Zoo in Lansing, MI about 2:15 p.m. myself, my daughter and granddaughter were getting ready to exit the hayride when I looked up at the sky to the North and saw two white cone shaped objects coming from the East going West. They were one behind the other and very close in proximity to one another when comparing them to any known aircraft. Planes do not typically fly that low or close together. We tried to determine if the objects had wings, but from our perspective we did not see any. They did not have any contrails either. As they were flying across the sky and behind the trees, I lost sight of them. A few seconds later a plane flew across the sky going East with a clear contrail. It was also at a much higher altitude than the two objects.
