In victory Stewart was as witty and gracious as ever, but he saved his best words for Andretti.
"It doesn't surprise me that he went fast," Stewart said, "only that he did it the first time out."
Andretti's feat took most of the attention away from what had been advertised as the week's main attraction—the close race for the Grand Prix driving title—but nothing could mask the weird new look of the racing cars.
At the Belgian Grand Prix in June the Ferraris of Chris Amon and Jackie Ickx suddenly appeared with huge airfoils, or wings, over their rear wheels. The theory was simple. The lightweight racers (minimum weight: 1,100 pounds) were getting airborne at high speeds, and the wing would create a downward thrust to keep a car on the ground. At the Glen every factory team had wings, plus anti-takeoff flaps up front.
