The U.S. Department of Homeland Security computer system that checks airline passengers against a terrorism watch list was running again Wednesday night after experiencing a technical glitch. Citing a Homeland Security official, NBC News reported the Customs and Border Patrol system error was not believed to be malicious. The system was back up after about 90 minutes, but not before causing delays for security screenings at New York City's John F. Kennedy Airport. Similar issues were reported in Boston, Dallas-Fort Worth, Charlotte, N.C. and Baltimore. A federal official said international passengers were still manually processed during the disruption. It's still unclear what caused the computer problem.
