Officials: Superbowl blackout caused by defect, human flaw

NEW ORLEANS, LA (WMBF) –The infamous blackout in the Mercedes-Benz Superdome during Super Bowl 47 was caused by a design flaw and human error, according to utility company Entergy New Orleans.

Officials say a recently-installed relay had a design-defect that caused it to trip in an unpredictable way, in addition to poor communication between the manufacturer and the utility company.

Power to half of the arena cut off early in the third quarter of the game between the Baltimore Ravens and the San Francisco 49ers.
