Helicopter crashes during the Iraq war and its aftermath:

— Nov. 15, 2003: Two U.S. Black Hawks crash in the northern city of Mosul (search), killing 17 soldiers and injuring 5, with one unaccounted for. A U.S. soldier says he heard one helicopter was hit by a rocket-propelled grenade, but a military spokesman says the cause has not been determined.

— Nov. 7, 2003: A Black Hawk is downed near Tikrit (search), apparently by a rocket-propelled grenade. The attack kills all six on board — four crew and two passengers from Department of the Army headquarters in Washington.

— Nov. 2, 2003: A Chinook (search) is shot down near Fallujah, killing 16 American soldiers and injuring 26. The military believes a SA-7 shoulder-fired missile slammed into one of the chopper's rear-mounted engines.

— Oct. 25, 2003: A rocket-propelled grenade forces down a Black Hawk north of Baghdad, and five soldiers are injured.

— May 19, 2003: A Sea Knight crashes shortly after takeoff in the Shat al-Hillah Canal in Hillah, about 60 miles south of Baghdad, killing four U.S. Marines. Another Marine drowns while trying to rescue them. The cause of the crash appears to be accidental.

— May 9, 2003: A Black Hawk crashes near Samara, between Baghdad and Tikrit, killing three U.S. soldiers. Reports indicate the crash was an accident.
