The U.S. Army on Friday made a highly unusual decision at the request of the family not to release the name of one of the three soldiers killed when a military Black Hawk collided with a passenger jet on Wednesday evening.

The crew of the Army Black Hawk helicopter involved in the deadly collision with a jetliner had thousands of hours of flight experience.

Investigators found the recording devices, or black boxes, from the American Airlines plane that collided with a helicopter Wednesday near Washington.
