The Willamette Aerostat Society (WAS) is a group of pilots, crewmembers, and families who enjoy the sport of hot air ballooning. Membership is open to the general public.

We are based in Oregon’s beautiful Willamette Valley, but we have members from a large geographical area. Our flying season usually runs from June to October.
