A San Rafael man died in a glider crash in Lake County Friday, authorities said.
According to a Lake County Sheriff's Office Facebook post, officers received a call from Williams Soaring Center in Williams, Calif. about an overdue aircraft.
The Soaring Center tracked GPS coordinates and traced the aircraft back to the area of Matthews Road in Lakeport where deputies then found the glider had crashed.
Upon arrival, deputies found the pilot, Matthew Herron, 89, deceased.
Herron was a photographer who covered the civil rights movement. He spent days capturing the 1965 voting rights march from Selma to Montgomery.
Some of his work was featured at an exhibition at the San Francisco Main Library earlier this year.
Officials say the glider took off from Lampson Airfield Friday afternoon and it was en route to Mendocino County.
The aircraft was described by authorities as a LAK-17B FES MINI Glider.
Lake County deputies say the Federal Aviation Administration and National Transportation Safety Board will investigate the crash.
This is the second aircraft crash in Lake County this week.
