The panel that oversees the Superdome in New Orleans holds its first regular meeting since the power outage that caused a delay in the third quarter of the Super Bowl. The Louisiana Stadium and Exposition District board meets at midday Wednesday at the state-owned dome. Entergy Corp. has said it believes the outage was caused by an electrical relay device it installed specially to prevent a power failure at the dome. But it's unclear whether the device had a design flaw or a manufacturing defect. Entergy and the management company that runs the dome for the state, SMG, recently hired Utah-based forensic engineer John Palmer to perform an independent analysis of the outage.
