This was kinda cool .. I'm working at my desk and I hear a different kind of airplane, not what I normally hear ..
My first thought, sounds like a '17 is running around, but both the EAA and CAF ones are not near here at this time of year. So .. what the heck, it gets a bit louder, and I turn around and see four airplanes, okay. So I was partially right. There were four engines, they just were not on the same airframe.

The irony .. a Quartet of Yakolev 52's.. A Y-52? ;-) They made many passes of the area. I just had to go out the front door and watch. Not very often when you get an air show without leaving your house. That was pretty cool.
