The Oregonian reports that a man from Oregon is among the 12 Marines missing after two helicopters crashed off Hawaii.

The newspaper identified the man as 21-year-old Ty Hart from Stayton, Oregon. He reportedly lives on base in Hawaii with his wife.

Family friend Christina Brown described Hart as upbeat and energetic and said he enjoys nature, boating and wakeboarding.

Hart's former high school football coach and teacher, Alan Kirby, says Hart was a positive kid who always had a smile on his face and called him a quick learner on the gridiron.

Officials are asking people to immediately report any sightings of possible debris from two Marine helicopters that crashed off Hawaii.

Honolulu Emergency Services Department spokeswoman Shayne Enright says debris sightings can be reported to 911 so that authorities can respond quickly.

Honolulu fire, police and ocean safety officials are helping the Marines and the Coast Guard with the search for survivors. Rescuers are contending with rough water conditions and poor visibility.

Enright says rescuers are hopeful survivors will be found.

Two Marine Corps helicopters carrying six crew members each went down off the Hawaiian island of Oahu while on a nighttime training mission just before midnight Thursday.

The 12 Marines remain missing. Their names haven't been released.

A civilian on a beach notified the Coast Guard about two Marine helicopters that crashed off Hawaii.

Coast Guard Lt. Scott Carr said at a Friday news conference that the person saw aircraft flying then disappear and a fireball.

Marine Capt. Tim Irish says the Marines were alerted when two helicopters didn't return to their base at Kaneohe Bay as scheduled. All 12 crew members were still missing Friday.

Carr says 10 to 12 knot winds and breaking surf up to 30 feet are complicating search and rescue efforts.

The Coast Guard initially reported that the choppers had collided, but Irish said later in the day that he did not know if the accident was a collision.

Two Marine helicopters collided off the Oahu coast in Hawaii, and rescuers were looking for the 12 crew members aboard.

Marine Capt. Timothy Irish said Friday that each helicopter had a crew of six from Marine Corps Base Hawaii. He says no other passengers were aboard either aircraft during the nighttime training mission.

Irish said officials spotted a debris area spanning about 2 miles, and the surf was choppy just before daybreak in Hawaii. The helicopters collided about 2 1/2 miles offshore around 11:40 p.m. Thursday.

The Coast Guard is the lead agency for the search. Irish says the Coast Guard has helicopters on scene and is coordinating with some Navy and Air Force aircraft.

A Honolulu Fire Department rescue boat also is searching.
