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 at the time because of fog and rain, according to a preliminary accident report released on Jan. 15.
The unidentified person was on a hiking trail Dec. 26 in Koke’s State Park on Kauai island and described hearing a hovering helicopter followed by a high-pitched whine, the National Transportation Safety Board report said.
