Caption: This submission goes into the "edge of sanity" bin: a wIngwalking airshow act on 8/19/07 at the Pease Air National Guard Base in Portsmouth, New Hampshire. The low cloud base in the distance gives the illusion that the picture is taken from aloft (instead of from the ground with the aircraft flying extremely low). Camera: Nikon D80, shutter priority, 1/500 second, f/7.1, ISO 100 with 18-200 mm VR lens.
