Make plans to celebrate 50 Years of Happiness!

The Hatz Biplane Association will be hosting this wonderful event at Wausau Downtown Airport (AUW). Hatz Biplanes will gather this year in the area where John Hatz first designed, built and flew his homebuilt biplane which was named Happiness! We will gather with friends and family of John Hatz and celebrate this remarkable milestone.

Plans are in place for a fly-out on Saturday with a stop at Heymeadow where John Hatz flew the original Hatz. Saturday evening dinner will be provided along with live music.

We would love to have you come and celebrate with us!
