Twice in the past 10 minutes I heard low-flying jets. I assume they are military although I haven't actually seen them.

All civilian aircraft in the United States have been on the ground for about an hour. There is a specific "no-fly zone" around Manhatten and D.C., and military aircraft are patrolling both NYC, D.C., and probably other large cities.
