The NTSB has finalized the results of its investigation into the helicopter crash that took the lives of Kobe Bryant, Bryant's daughter, and seven others. The board found earlier this month that pilot error was the most significant reason for the crash.

A helicopter pilot's "spatial disorientation" played a key role in the crash that killed basketball legend Kobe Bryant, his daughter and several friends last year, federal authorities said Tuesday.

The cause of the helicopter crash that claimed the lives of Kobe Bryant, his 13-year-old daughter, Gianna Bryant, and seven others was one that commonly occurs with pilots: he felt unnecessary pressure to fly despite questionable weather, according to a final report issued by the National Transportation Safety Board.

The U.S. safety investigators found that the pilot of Kobe Bryant’s helicopter, Ara Zobayan, flew through the clouds in violation of federal standards and likely became disoriented, not knowing ‘which way was up,’ before crashing into a hillside, killing all 8 passengers on board.
