A Pair of Airplanes

While I was waiting for the Alpena, I heard the buzzing sounds of airplanes.

 I'm not sure what kind of plane this is.  It is definitely a type of floatplane but I'm not sure what kind it is.  If I had an N number, I could tell you.

I think this is a Stinson 108.  It looks like it has larger tires for bushplane operations.
