The off-duty pilot who attempted to crash a San Francisco-bound flight was having a “mental breakdown,” witnesses said. The pilot, 44-year-old Joseph Emerson, told police that he consumed psychedelic mushrooms 48 hours before the flight and has suffered from depression for a long time. Experts said it’s doubtful that Emerson would’ve still been under the influence two days after consuming the drugs, but the psychedelics could’ve further destabilized an already fragile mental condition.
