Tuesday’s airshow was just for practice, but Wednesday the real show begins at 11 a.m. The free Atlantic City Airshow returns to the skies above the boardwalk for five hours of exciting maneuvers by aircraft from all five military branches. Last year an estimated 400,000 people flocked to Atlantic City for the aerial spectacle. The show closes out with a demonstration by the U.S.A.F. Thunderbirds.
