Zenith Aircraft is organizing their eighth annual “Fly in to Summer” Open Hangar Day and Fly-In Gathering at the Zenith Aircraft kit factory in central Missouri in June. This will be a fun gathering of Zenith builders, flyers, and enthusiasts, and is an informal grass-roots fly-in gathering open to all aviation enthusiasts: Visit the factory, see the new Zenith demo planes, and meet with fellow builders and pilots. In contrast to the annual fall Open Hangar Day (with scheduled workshops and forums), the June event is very informal and unstructured: Owners of completed Zenith Aircraft are encouraged to fly-in to show off their completed project to fellow builders. The Zenith Aircraft factory will be open from 8:00 am – 2:00 pm for self-guided factory tours.
