The United States National Transportation Safety Board, NTSB, has released images of the site where the helicopter carrying Access Holdings Chief Executive Officer, Herbert Wigwe and others crashed.
The images by NTSB showed investigators combing through wreckage at the site.
Graham emphasised the agency’s commitment to a meticulous examination of the scene, saying the team conducted aerial drone mapping and documented the wreckage.
The Airbus EC130 helicopter crashed close to the California-Nevada border near Halloran Springs, killing Wigwe, his wife Doreen, their son Chizi Wigwe and former Nigerian Exchange Group Chairman Abimbola Ogunbanjo.
It would be recalled that Michael Graham, board member with the NTSB, provided an update on Sunday when he said they had visited the site and outlined the activities conducted on the first full day of investigation at the accident site.
These included aerial drone mapping, site documentation, and a detailed examination of the debris field by the airworthiness group.
The debris field, approximately 100 yards in length, contained all major components of the helicopter, including rotor blades, transmission, engine, tail rotor, landing gear skids, and various avionics components.
