UFO falling from the sky spotted in Duluth, Minnesota

On February 12, 2017, a witness has caught a photo of a strange thing dropping out from the sky. He thinks it was just a regular aircraft but when we look close, it seems to be UFO…

Witness report:

I took this picture yesterday because the craft appeared to be moving vertically and it caught my eye. My lens was dirty, but the image is good quality. I am sure it is just a regular aircraft, but I am curious and hope to get some feedback on it.
