HONOLULU -- Firefighters, police and state land officers joined the Coast Guard recovery efforts to search for a missing rescue team member.

The Coast Guard's helicopter crew crashed during routine exercises.

The Coast Guard and fellow agencies, like the Honolulu Fire Department, are searching for people who have a similar mission -- to help and rescue those in need.

"It's emotional. It hits home when we are working on a rescue that involves our peers," HFD Capt. Terry Seelig said.

Working on little sleep, crews set up a command center at Keehi Boat Harbor, searching past midnight and again at daylight. In total, 20 firefighters and state land officers in several boats and a helicopter joined the Coast Guard's efforts.

"We care deeply about these people and we are doing everything we can to support them in recovering their lost crew members," Seelig said.

Firefighters said the Coast Guard gives them search parameters based on the weather, ocean conditions and the debris field. Computer models predict where the wreckage is heading. The search area is 30-square nautical miles.
