An off-duty pilot accused of attempting to disable a plane’s engines mid-flight told investigators he believed he was dreaming and had taken “magic mushrooms” 48 hours before the incident, according to state court records obtained by CNN.
Joseph D. Emerson, 44, attempted to cut fuel to the Alaska Airlines plane’s engines while the flight was en route from Washington state to San Francisco on Sunday, authorities say. The quick actions of the aircraft’s captain and first officer kept the engines from failing completely, the airline said.
Emerson told investigators he “had consumed ‘magic mushrooms’ approximately 48 hours before the incident on the plane,” an affidavit filed by prosecutors states. He also said he had been awake for the last 40 hours, according to a separate federal court document.

Emerson told police he thought he was dreaming and believed pulling the handles of a fire extinguishing system — which cuts fuel to the aircraft’s engines — would cause him to “wake up,” state court documents say.
Emerson was riding in the cockpit in a jump seat, as is permitted for off-duty pilots, and a confrontation began when he reached for the fire controls, according to the documents.

As Emerson reached for the controls, one of the pilots “grabbed Emerson’s wrists and (the other pilot) reported that they wrestled with Emerson for a few seconds before Emerson stopped and said he was OK,” the documents state, adding “Emerson was not able to pull the handles all the way down before the pilots intervened”.
Emerson had experienced depression and the recent death of a friend, the documents say. He said he was having a nervous breakdown and told the flight crew he needed to be subdued, according to a separate federal criminal complaint.

It’s highly unlikely that psilocybin — sometimes called “magic mushrooms” — would still be in the pilot’s system 48 hours after use, but it’s possible he could have been feeling the lingering effects of the drug, said Matt Johnson, a Johns Hopkins professor who studies psychedelics and other drugs.
Johnson likened mushroom use to drinking alcohol — while a person is no longer drunk the day after drinking, the hangover caused by alcohol could impair their behaviour or ability to function.
It’s possible that the lingering effects of psilocybin, existing depression and sleep deprivation could have created a “perfect storm”, in which Emerson was experiencing behavioural changes or derealisation, Johnson said.
Derealisation is a feeling of detachment from one’s surroundings. People often describe the experience as feeling as though they’re in a movie or a dream. “Psychotic-like behavior” is among the risks of taking psilocybin, particularly for those with existing psychiatric disorders, said Johnson.
Emerson has been charged in federal court with interfering with a flight crew, the US Attorney’s Office for the District of Oregon announced Tuesday. That charge comes on the heels of dozens of state charges filed in Oregon, including 83 felony counts of attempted murder, 83 counts of reckless endangerment and one count of endangering an aircraft, booking records show. He pleaded not guilty to all state charges Tuesday.

After the cockpit confrontation, Emerson was taken to the rear of the aircraft, but then attempted to grab the handle of an emergency exit during the flight’s descent, according to a release from the US attorney’s office.
The flight diverted to Portland, Oregon, where Emerson was taken into custody by Port of Portland police, the agency said in a statement.
While in custody, Emerson told a police officer he became depressed about six months ago, according to an affidavit authored by an FBI agent and included alongside the federal complaint. Emerson denied taking any medications, the affidavit says, but he did discuss psychedelic mushrooms with the responding officer.
“The officer and Emerson talked about the use of psychedelic mushrooms and Emerson said it was his first time taking mushrooms,” the affidavit says.
Asked specifically if Emerson told officers he had been under the influence of mushrooms at the time of the incident, a spokesperson for the US Attorney’s Office in Oregon told CNN that remains part of their ongoing investigation.
While in custody, Emerson said he was “admitting to what I did,” per the affidavit. “I’m not fighting any charges you want to bring against me, guys,” he said.
Emerson is being held without bail at the Multnomah County Jail and appeared in court on Tuesday wearing a blue jail uniform with his hands restrained behind his back.
His release was not addressed at Tuesday’s hearing, said Multnomah County Circuit Court Judge Jenna Plank, noting his case requires a “more robust release hearing” within five days. Online records do not list an attorney for Emerson, and CNN has been working to determine if he has legal representation in both state and federal court.
Authorities do not believe the incident was an act of terrorism or ideologically motivated violence, a law enforcement source familiar with the investigation told CNN. Investigators believe it may have been the result of a mental health episode, and authorities are preparing for court officials to order an assessment of the defendant’s psychological state as part of court proceedings, the source said.
Suspect tried to cut the engine fuel, airline says
After taking off from Everett, Washington, Alaska Airlines Flight 2059 — operated by regional carrier Horizon Air — reported a “security threat related to an off-duty Alaska Airlines pilot, identified as Emerson, who was travelling in the flight deck jump seat,” the airline said in a statement.
While in the cockpit, Emerson had tried to shut down both of the Embraer 175’s engines by pulling its fire extinguisher handles, the airline said.
“The fire suppression system consists of a T-handle for each engine; when pulled, a valve in the wing closes to shut off fuel to the engine,” Alaska Airlines said in a statement to CNN. “After they are pulled, some residual fuel remains in the line.”
The airline said the quick reaction of the crew to reset both handles helped restore the flow of fuel and prevented the engines from cutting out.
Emerson initially had engaged the pilots in small talk about the weather and the aircraft, the affidavit says. He then said, “I’m not OK,” and one of the pilots turned around to see him reaching up and grabbing the red fire handles, the affidavit says.
One of the pilots grabbed Emerson’s wrist while the other declared an in-flight emergency, the affidavit says. One pilot said Emerson “initially resisted,” and the two “wrestled” for about half a minute before Emerson agreed to leave the cockpit.
“I think he’s subdued,” one of the plane’s pilots can be heard saying in air traffic control audio recorded by LiveATC.net. “Other than that, we want law enforcement as soon as we get on the ground and are parked.”
After “peacefully walking to the back of the plane,” the affidavit says Emerson told a flight attendant, “You need to cuff me right now or it’s going to be bad.”
The crew cuffed his wrists, but during the descent, Emerson “turned towards an emergency exit door and tried to grab the handle,” and was stopped by a flight attendant, the affidavit says.
“Another flight attendant observed Emerson make statements such as, ‘I messed everything up’ and that ‘he tried to kill everybody,’” the affidavit says. “Emerson was heard saying he had just put 84 peoples’ lives at risk tonight, including his own.”
When the flight landed at Portland International Airport about 6.30pm, Emerson was taken into custody by Port of Portland police officers, the port said.
No injuries were reported on the flight, the FBI said.
All passengers were later able to fly to San Francisco with a new crew and aircraft, the airline said, noting it is “reaching out to each of them individually to discuss their experience and check-in on their well-being.”
Passengers describe emergency
Two passengers on the flight told CNN that the airline crew maintained a calm environment on the plane as the incident played out.
Aubrey Gavello, one of the passengers, said she didn’t realise something was wrong until a flight attendant announced over the loudspeaker that the plane needed to land immediately.
“We didn’t know where we were landing, and we didn’t know what was wrong. But (the flight attendant) assured us we were safe,” Gavello said on CNN’s Laura Coates Live on Monday night.
Later, the pilot informed passengers through the loudspeaker that there had been a “disturbance in the cockpit”, said Alex Wood, who was seated at the front of the plane. Wood said he was wearing headphones and slept through the incident.
“I was right by the cockpit, but nothing woke me up. Nothing was loud enough, nothing was rambunctious enough to wake me up,” Wood said.
‘It was very shocking,’ suspect’s neighbour says
Emerson’s neighbour, Ed Yee, told CNN it was “very shocking” to hear of the suspect’s alleged actions. “He seems like a really nice guy. Nothing abnormal about him,” Yee said.
Emerson had his most recent FAA medical examination last month, records show. He has a first-class medical certificate, the highest level of medical certificate awarded by the agency, which requires examinations every six months for pilots 40 and over.
Emerson has worked in aviation for at least two decades, according to information shared by Alaska Airlines.
“Throughout his career, Emerson completed his mandated FAA medical certifications in accordance with regulatory requirements, and at no point were his certifications denied, suspended or revoked,” Alaska Airlines said in a statement.
