It had taken off from the town of Lihue.No emergency signals were received from the helicopter, which has an emergency electronic locator.Coast Guard and US Navy helicopters were joined by a Coast Guard cutter in the search, with resources now focusing on finding any possible survivors.Steep terrain, low visibility, choppy seas and rain have made the search more difficult, the agency said.Helicopter tours are common above Kauai.

Much of the island is a state park because of its stunning scenery, with parts which featured in the film Jurassic Park.
