When was the first oil shipped via the Big Inch pipeline?

• A. June 1940
• B. December 1941
• C. August 1943
• D. January 1945

Answer: (C)

The first oil shipped via the Big Inch occurred in August 1943. This reflects a wartime milestone: after construction began in 1942, the line was completed and brought into operation by mid-1943, allowing crude to move directly from Texas to the Northeast. This inland transport reduced reliance on vulnerable sea routes through the Atlantic, keeping Allied refineries supplied during heavy U-boat activity. Earlier dates don’t fit because the pipeline didn’t exist yet, and later dates miss the moment when the line first carried oil.
