FAA orders no-fly zone over Boston explosion site

The Federal Aviation Administration is warning pilots that it has created a no-fly zone over the site of two explosions at the annual Boston marathon.

The agency said in a notice issued Monday about an hour after the explosions that a no-fly zone with a 3.5-mile (5.6-kilometer) radius has been created over Boylston Street. The notice says the no-fly zone is effective immediately and will remain in effect until further notice. Pilots planning flights were urged to call their local flight service station. (AP)
