The remains of six people have been found after a helicopter heading to one of the most rugged and remote coastlines in Hawaii crashed.
Officials said there are no indications of survivors after the incindent at the top of a mountain on the island of Kauai.
A search for the last person yet to be recovered would resume in the morning depending on weather.
A search began for the helicopter carrying a pilot and six passengers from two families after it was reported missing on Thursday evening from a tour of Kauai’s Na Pali Coast.
Two passengers are believed to be minors, the Coast Guard said.
The helicopter company, identified as Safari Helicopters, contacted the Coast Guard at about 6pm Thursday to say the aircraft was about 30 minutes overdue, authorities said.
A person who answered the phone at a number listed for Safari Helicopters declined to comment and hung up.
According to a preliminary report, the pilot said the tour was leaving the Waimea Canyon area, known as the “Grand Canyon of the Pacific,” at about 4.40pm, which was the last contact with the helicopter.
The Eurocopter AS350 has an emergency electronic locator transmitter, but no signals were received.
The FAA requires the locators to be able to withstand impact.
However it is possible for the device to stop working in an extreme crash, Mr Gregor said.
The FAA is investigating along with the National Transportation Safety Board (NTSB).
