United States GP West, Circuit Long Beach, April 3, 1977

An already tragic Formula One season received exactly what it needed to chase away the despair when the brilliant Mario Andretti became the first American to win a Grand Prix on his home soil. After the deaths of Tom Pryce in the South African race and Carlos Pace in a plane crash, the United States Grand Prix West was a glorious triumph for Andretti. It was the start of his two-year march to the World Championship, and the first win for the car that would usher in the ground-effects era, Colin Chapman's Lotus 78.
