LOS ANGELES, California — New details are emerging from the helicopter crash that killed basketball legend Kobe Bryant and eight others.
In preliminary documents detailing the investigation, the National Transportation Safety Board said weather and visibility were a concern.
Leading up to the flight on January 26, both the pilot, Ara Zobayan, and the flight coordinator dismissed weather concerns.
Documents also suggest, that before the chopper crashed into a hillside near Los Angeles, Zobayan appeared disoriented by fog.
He told air traffic controllers that he was climbing to four thousand feet when he was actually descending.
Investigators said the pilot may have misperceived the pitch and roll angles.
These documents are not the final report in the case which will determine the exact cause of the crash.
