Multiple federal, state, and local agencies and K-9 teams found nothing unusual in a search. At 8am, some 200 people stood about a quarter-mile from the terminal, the AP reports via USA Today; they appeared calm. Officials were "nice enough, just telling us they're clearing this, clearing that," says a passenger. At least a dozen flights were delayed, the Richmond Times-Dispatch adds, and the terminal was reopened at 9:30am. It's not the only aviation disturbance this morning: CNN is reporting that an explosion in a maintenance shed has shut down power to a concourse at Atlanta's Hartsfield-Jackson International Airport. The concourse was evacuated as a precaution.
