While the 60th EAA AirVenture didn’t disappoint in the normal arenas of kitbuilt aircraft, workshops, new light sport aircraft, ultralights, warbirds, stirring airshow aerobatics, a performance by the Steve Miller Band, outdoor movies, bratwurst roasting on the grill, 200 Piper Cubs, heat and thunderstorms and more, there were signs that this show is changing. The prominent new chalets on the front line of the flight line were an obvious change. That they were comfortably air-conditioned offered relief to show-goers who were invited inside, especially on the broiling Monday and Wednesday of the show. But there were other, more subtle signs of the growing importance of AirVenture on the show circuit.
