A former off-duty Alaska Airlines pilot who tried to crash a San Francisco-bound flight by shutting off the engines while on a sleepless bender fueled by psycahdelic mushrooms won’t serve any additional prison time, a federal judge ruled.

Joseph Emerson was sentenced Monday to time served and three years’ supervised release by US District Court Judge Amy Baggio in Portland, Oregon — dodging a year of prison time sought by federal prosecutors.

“Pilots are not perfect. They are human,” Baggio said. “They are people, and all people need help sometimes.”

Emerson was subdued by the flight crew aboard a Horizon flight from Everett, Washington to San Francisco on Oct. 22, 2023, after trying to cut the engines while riding off-duty in the cockpit.

He told police that he was grieving his friend and had taken psychedelic mushrooms two days earlier and hadn’t slept in over 40 hours when he tried to pull the hijinx on the flight with over 80 passengers on board.

Emerson recalled believing he was dreaming and tried to wake up by grabbing two red handles that could have activated the fire suppression system and cut fuel to the engines.

Had he been successful, he would have immediately cut off the flow of fuel to the engines.

The flight was diverted and landed in Portland after the harrowing ordeal.

His attorney, Ethan Levi, described Emerson’s actions as “a product of untreated alcohol use disorder.” The distressed pilot had been drinking and accepted mushrooms “because of his lower inhibitions.”

Emerson spent 46 days in jail and was released pending his trial in Dec. 2023, with the court ordering him to stay sober from drugs and alcohol, undergo mental health services, and stay away from aircraft.

He went to treatment after jail and has been sober since, Levi said.

Before he was sentenced, Emerson said he regretted the harm he caused.

“I’m not a victim. I am here as a direct result of my actions,” Emerson told the court. “I can tell you that this very tragic event has forced me to grow as an individual.”

His wife, Sarah Stretch, also told the courtroom that she was proud of how her husband had grown since the incident.

“I am so sorry for those that it’s impacted as much as it has,” Stretch said.

One of the pilots aboard the Horizon Air flight, Alan Koziol, recalled not believing that Emerson had been trying to hurt anyone by reaching to cut the engines, and that he seemed “more like a trapped animal than a man in control of his faculties,” he recalled.

Kozial maintained that while pilots bear an “immense responsibility,” the aviation industry should allow pilots more freedom to seek mental health care.

Geoffrey Barrow, assistant US attorney in the district of Oregon, said Emerson’s actions were serious and that the crew “saved the day by intervening.”

“There were 84 people on that plane who could have lost their lives,” he said.

A passenger aboard the flight, Alison Snyder, told the courtroom over the phone that she and her husband will never feel safe flying again after Emerson pulled the near-catastrophic maneuver.

“Because of Joseph Emerson’s actions that day, we will never feel as safe flying as we once did,” she said.

Emerson pleaded guilty in September to all charges against him as part of an agreement with prosecutors.

He faced federal charges of interfering with a flight crew. A state indictment in Oregon separately charged him with 83 counts of endangering another person and one count of endangering an aircraft.

On the state level, he was sentenced to 50 days in jail, with credit for time served, and five years of probation.

The state court also ordered him to complete 664 hours of community service, half of which he can serve at his own pilot health nonprofit, “Clear Skies Ahead.”

He will additionally shell out $60,000 in restitution, mostly to Alaska Air Group, and abide by provisions on drugs, alcohol, mental health treatment, and avoiding aircraft, the state ordered.

Showers could linger in Los Angeles on Tuesday following four straight days of rain — and even more rain is likely on Thursday and Friday.

There’s a 20% to 30% of showers and thunderstorms Tuesday across much of Los Angeles County, the National Weather Service said, although it’s expected to be mostly sunny. The thunderstorms will remain a slight risk because of a cold front that ushered in unstable air Monday.

By Tuesday, the cold front will have moved away from L.A., but the cold core of the low-pressure system will still be around. “This will bring enough instability to the area for a slight chance of thunderstorm development,” the weather service in Oxnard said.

Temperatures have chilled with the latest storm. While the L.A. coast and San Gabriel Valley on Monday reached the mid-60s, due to late arriving rain, most of L.A. County’s coastal areas and valleys “struggled to get out of the 50s,” the weather service said.

Wednesday will bring a reprieve with sunny skies, but another storm is expected to enter Southern California on Thursday and continue through Friday.

Thursday’s storm is expected to drop from 0.25 to 0.75 inches of precipitation. That’s on top of the 0.74 inches of rain that fell on downtown L.A. in the 24-hour period that ended at 9 p.m. Monday. Before that, the weekend storm that began Friday brought 2.68 inches of rain to downtown.

For the 24-hour period ending 9 p.m. Monday, Porter Ranch received 1.61 inches; La Cañada Flintridge, 1.5; Northridge, 1.43; Bel-Air, 1.21; Castaic, 1.15; Van Nuys, 1.12; and Beverly Hills, 1.11.

Warm Springs Camp, in the mountains overlooking the Santa Clarita Valley, recorded an 18-hour rainfall total of 2.5 inches by Monday evening.

The storms, thus far, have caused some mayhem but no severe or life-threatening damage in recently burned areas.

By late Monday night, landslides and flooding were reported on a number of roads. The 5 Freeway near Highway 14, between Sylmar and Santa Clarita, suffered flooding Monday afternoon, as did an offramp on the 91 Freeway at Carmenita Road. The California Highway Patrol said there was flooding at onramps to the 10 Freeway in El Monte and the 605 Freeway on the southern border of Baldwin Park.

Mountain roads were hard hit. One motorist on Angeles Crest Highway, a road that winds through the San Gabriel Mountains, became “stuck in mud, dirt and rock” in a northbound lane, while the southbound lane was completely blocked with multiple landslides, according to reports filed to the National Weather Service. Snowplows couldn’t haul away the debris because it was too heavy.

Near the 101 Freeway in Hidden Hills, a number of vehicles hydroplaned as Round Meadow Road flooded near Mureau Road.

Monday afternoon and evening also brought rockslides or mudsldies to San Francisquito Canyon Road, the mountainous route that connects Santa Clarita to the Antelope Valley; a section of Kanan Dume Road, which leads into the Santa Monica Mountains from Malibu; and on Mulholland Highway south of Calabasas.

Snow levels were at around 7,000 feet on Monday but were expected to drop to 5,000 feet by Tuesday. Officials issued a winter weather advisory for the eastern San Gabriel Mountains and the northern Ventura County mountains that is set to last through Tuesday night. About 2 to 5 inches of snow could fall in the mountains.

“As for the Grapevine area, there is a chance of a dusting of snow Tuesday morning as the snow levels lower,” the weather service said. The Grapevine is a key travel corridor on the 5 Freeway that connects L.A. and Santa Clarita with the Central Valley and the San Francisco Bay Area.

The highest point of the Grapevine section is the Tejon Pass, which peaks in elevation at 4,144 feet above sea level. At that location, “some non-accumulating snow is possible,” the weather service said.
