This was my second time volunteering the 182 and myself to fly kids with special needs for the Challenge Air event at KPAE. The event was hosted by Historic Flight Foundation and their hangar and ramp was transformed from museum to a carnival experience. The event attracted 100's of families who came out for aviation related crafts, education, and of course a scenic flight in a GA aircraft. I flew six flights today and nothing but smiles from the children and parents on board.
