“A person who was near a remote Hawaii site where a tour helicopter crashed and killed seven people last month told investigators that visibility was only about 20 feet (6 meters) at the time because of fog and rain, according to a preliminary accident report released Wednesday.
The unidentified person was on a hiking trail Dec. 26 in Koke’e State Park on Kauai island and described hearing a hovering helicopter followed by a high-pitched whine, the National Transportation Safety Board report said.
The person was about 1.5 miles (2.4 kilometers) away from the remote mountain ridge where the helicopter went down. The witness tried to look for the helicopter but could not because of the weather conditions and fading daylight, the report said.“
