The cause of the blackout that cost the Ravens so much of their energy and momentum in Sunday night's Super Bowl was revealed on Friday.
In an Associated Press story, the company which supplies the energy for the building said a "device designed specifically to prevent a blackout failed and plunged the game into darkness for more than half an hour."
Entergy New Orleans confirmed in the story that this device, which is called a "relay" had actually been put in to help the Superdome not have problems with the cable which connects its "Incoming power line with the lines that run into the stadium."
But it didn't work correctly, thereby causing the 34-minute delay in play early in the third quarter, after the Ravens had taken a 28-6 lead over the 49ers. The Ravens eventually held on for a 34-31 victory in Super Bowl XLVII.
The power failure put about half of the stadium into darkness during that time period.
The article also said that officials in New Orleans apparently had concerns that this might affect the city's chances of hosting another Super Bowl. But commissioner Roger Goodell said the NFL still would consider New Orleans to host a Super Bowl again. Mayor Mitch Landrieu said in the article that they're going to make a bid for the game once more in 2018.
