WASHINGTON (CNN) - An electrical failure at Ronald Reagan Washington National Airport interrupted flights and prompted additional security measures for a short time Monday, airport officials told CNN.
Metropolitan Washington Airports spokeswoman Courtney Mickalonis said the airport was put in a ground stop halting all arrivals and departures.
Le-ha Anderson with Dominion Power said power was restored after crews found the problem.
"They were able to identify a piece of equipment within the airport system," she said.
She said there was no interruption in service leading to the airport.
She said the outage started at 12:25 p.m. ET and power was re-energized at 1:27 p.m.
Transportation Security Administration workers allowed those who had already cleared security checkpoints to remain in gate lounge waiting areas, but those who had not passed screening were blocked from entering the secure zones at the airport until power was restored.
