After the September 11, 2001 attacks, all commercial flights in the United States were grounded for a total of about three days. The Federal Aviation Administration (FAA) ordered a nationwide grounding of all aircraft on September 11, and flights gradually resumed on September 13, 2001. However, airspace over Washington, D.C., and New York City remained restricted for a longer period as security measures were heightened.
