A Little Afternoon Planewatching

I heard a plane buzzing around the office this afternoon, so I decided to grab my camera and see what it was about.

 The plane in question wasn't this Boeing 737 belonging to Southwest Airlines but I figured I might as well get a shot of it.  I think this plane was taking off from Detroit Metro but I'm not sure where it was heading.

 It might have been this Cessna 172 flying out of Ann Arbor Airport.

It definitely wasn't this plane belonging to American Airlines that was just passing through.
