i was siting on my front porch smoking a cigarette and i noticed an oddly colored light flying very fast westbound, it then changed direction towards south. i stood and went to take a picture with my cell phone but it would not detect the light even though i could clearly see it and assumed my phone could too. i then sat back down, and when i looked back up it had disappeared. the light was like nothing i've seen flying over mid-michigan and it was flying much faster and changed direction in a way that is currently not possible by our own aircraft (close to if not a 90 degree turn). i truly felt this was a ufo, because i have watched the nights sky almost everynight observing the stars and airplanes flying over the state of michigan and this object had no similarities to anything i've ever seen.
