Oval over Monee, IL

The report, as filed

I saw two flying objects; one trailing white smoke and one trailing black. The objects were both moving in the same direction and looked like they were descending quickly. The second object (trailing black smoke) was far behind the first object, however, it was moving very quickly and soon passed up the first object. I thought they were planes at first, and I thought it was odd that they were so close together. I also thought that the object trailing black smoke might be a plane that was crashing because I've never seen a plane move that fast. Soon after the second object passed the first object, the first object (that was trailing the white smoke) glowed very brightly for about a minute and then disappeared. Less than a minute later, the object trailing the black smoke also disappeared. The sky was clear and the trails of smoke came to an abrupt stop. They did not reappear.
