More than 2,000 people are gathering at Pearl Harbor on Friday to mark the 71st anniversary of the Japanese attack that killed thousands of people and launched the United States into World War II.
Ceremonies get under way with a moment of silence at 7:55 a.m., the exact time the bombing began in 1941.
The crew of a Navy guided-missile destroyer will stand on deck while the ship passes the USS Arizona, a battleship that still lies in the harbor where it sank decades ago.
Hawaii Air National Guard aircraft will fly overhead in missing man formation.
The Navy and National Park Service are hosting the ceremonies, which are being held in remembrance of the 2,390 service members and 49 civilians killed in the attack.
Friday events will also give special recognition to members of the Women Airforce Service Pilots, who flew noncombat missions during World War II, and to ray Emory, a 91-year-old Pearl Harbor survivor who has pushed to identify the remains of unknown servicemen.
