One of These Things is Not Like the Others

 I am starting to see more helicopters fly by Belle Isle as I take pictures of ships.

I think this is a Robinson R44 and it operates from Detroit City Airport.

I'm not sure who owns it.

This is another Robinson R44 and it comes out of Grosse Ile.

I see this helicopter fairly often.

And I know it runs tours.

The first helicopter I saw.  It was up again.

I'm not sure who this helicopter belongs to.

As I was taking a picture of one of the ships, I saw this guy fly over.  It was an A330 and I think it was arriving from Amsterdam.
