The single-engine Aviat A1 plane crashed while attempting to pick up an advertising banner.
The pilot, who was the only one aboard, was killed in the crash while another person on the ground sustained non-life-threatening injuries.
According to Los Angeles County Aviation Commission official Dennis Lord, “For some reason, he turned loose of the banner. He was down at a very slow speed. The aircraft stalled and impacted the ground. Why is yet to be determined.
