WAIMEA, Hawaii (AP) _ A seriously injured pilot worked his way through more than a mile of dense rain forest seeking help for a couple injured when his small plane crashed, killing one man, authorities say.

William Merrill, with cuts and head and chest injuries, made his way to a house Wednesday after his sightseeing plane was thrown out of control by an updraft and crashed on Hawaii Island, said Sgt. William Aiona.

It took rescuers nearly three hours to carry out the victims. High wind and fog prevented a helicopter rescue, said fire Battalion Chief John Ide.

Merrill, 51, and Steve Manthey, 35, and his wife Jannet, 36, of Chicago, were in serious but stable condition at Lucy Henriques Medical Center, officials said.

Scott David Nell, 46, of The Dalles, Ore., died in the crash, police said.
