The pilot known for the "Miracle on the Hudson" is throwing his weight behind Joe Biden as the race for the White House enters the home stretch.

"Leadership is not just about sitting in the pilot’s seat,” said the opening lines of a new Lincoln Project ad starring the Bay Area’s own Capt. Chesley Sullenberger. "Sully," as he’s affectionately known, famously guided US Airways Flight 1549 to a safe water landing on the Hudson River in New York City in January 2009.

In referencing his service in the U.S. Air Force, Capt. Sullenberger continued: "I knew that serving a cause greater than oneself is the highest calling. And it’s in that highest calling of leadership that Donald Trump has failed us so miserably."

Watch the scathing ad below.

The retired pilot has not previously shied from sharing his opinion of the president.

Capt. Sullenberger formally endorsed Biden in February.
