Closest thing i found: "In the late 1950s, two scientists, Carl Clark and James Hardy, had a more daring idea. Physics dictated that if a spacecraft could be steadily accelerated at 2 Gs, it could reach the moon or Mars in days or even hours. But could a human being survive the constant acceleration? Clark used the centrifuge to find out. “He essentially moved into the cab, brought his La-Z-Boy from home, and stayed in there at 2 G for 24 hours,” says Shender. Clark slept, ate, worked, and lived at two Gs for a full day under constant medical surveillance. He suffered nothing more than fatigue. Further marathon rides were planned, but more immediate space missions loomed and the idea was set aside.
