An pilot repeatedly screamed 'mayday!' moments before his small plane crashed off the California coast, killing him, his pregnant wife and an Arizona father traveling with his three adult sons.

Landon Baldwin gave the anguished cry as he and wife Torrie went down over the Pacific Ocean just off the coast of San Diego Sunday afternoon.

George 'Jeremy' Bingham, 48, and his sons, George 'Bailey,' 26, Gavin, 24, and Ayden, 20, were also killed when the small Cessna slammed into the specific.

All six passengers perished in the devastating crash just three miles from the shore, according to a GoFundMe for the grieving family.

'This devastating loss has left behind a heartbroken family,' the fundraiser, organized by Hope Lofgreen, said.
