Another day at the (Omaka Aviation Heritage Centre) office:

By the way, the area between the camera and the fence is available before and during the show (or any time at all actually) for good viewing of aircraft activity. The hangar containing the black triplane replica is the first of four immediately behind the OAHC, and doors for the flyable aircraft in the OAHC are to the left also. Access to the runways is to the right. Most joyrides (e.g. in the Stearman just visible in the video) depart from this area.
