Black Hawk Helicopter Pilot Made 'Grave Error'—Father of Plane Crash Pilot

The father of Sam Lilley, one of the pilots of the American Airlines flight that collided with an Army Black Hawk over Washington, D.C., on Wednesday, has suggested the helicopter pilot made a "grave error" leading to the crash.

Timothy Lilley made the comment during an interview with local network Fox 5 Atlanta.

Newsweek contacted the Federal Aviation Administration (FAA) for comment on Friday via email outside of regular office hours.
