Grant Thompson, the American cinematographer and host of the National Geographic series "Limitless," died in a helicopter crash near the Sevier River in Utah on July 30, 2019. This verified explainer outlines the sequence of the rescue and recovery, the findings of the subsequent investigation, and the factors confirmed by authorities. The following content relies on official reports, law enforcement statements, and documented records to provide a clear, factual account of what happened, how the incident unfolded, and what is known with certainty.
Key Facts and Verified Timeline
On the evening of July 30, 2019, Grant Thompson and a professional pilot departed from a private airstrip near Sevier, Utah, on a routine helicopter flight. Shortly after takeoff, the aircraft encountered difficulty, leading to a controlled crash in a canyon approximately 150 feet below the rim. Emergency crews responded promptly, and Thompson was extricated from the wreckage. He was transported by medical helicopter to a hospital, where he was later pronounced deceased. Investigations concluded that pilot spatial disorientation and challenging terrain were contributing factors, with no evidence of mechanical failure or intoxication.
