Tennessee Blackout

June 10, 1942

From Memphis to Bristol, Tennessee blacked out for 30 minutes last night in the first test of its kind since the war began, a move designed to train the state’s 3,000,000 inhabitants how to blind the eyes of enemy bombers if the emergency should ever arise.

Promptly at 9 p.m., lights were switched off and a blanket of Stygian darkness, 432 miles long and 104 miles wide, descended across the state from the Great Smokey Mountains on the east to the Mississippi River on the West.
