Four people died after a military-contracted helicopter crashed at a U.S. naval facility in Kauai, Hawaii, officials announced on Wednesday.
The crash took place at the Pacific Missile Range Facility, a Navy base in Kauai, shortly after 10 a.m. local time Tuesday morning, according to officials.
The helicopter was operated by Croman Corporation, which "provides range support services" to the base, a Pacific Missile Range Facility spokesperson said in a statement, adding that names of the victims have not yet been released.
Furthermore, the spokesperson pointed out that the helicopter was taking part in a range training operation on the base in Kekaha when it crashed on the northern area of the installation.
Brian Beattie, the company's director of operations, stated that all crew members were Croman employees.
"The helicopter was conducting routine training operations under contract to the U.S. Navy," Beattie noted. "No further details are available."
The Pacific Missile Range Facility spokesperson affirmed that an investigation is underway to determine the cause of the accident.
In the same vein, the National Transportation Safety Board also asserted that it is investigating the crash of a Sikorsky S-61N helicopter near Kekaha.
Pacific Missile Range Facility is the "world's largest instrumented, multi-dimensional testing and training missile range," according to the U.S. Navy. It has over 42,000 square miles of controlled airspace.
