A federal judge has decided that a former Alaska Airlines pilot who tried to cut the engines of a passenger flight in 2023 won't serve prison time. Joseph Emerson was sentenced Monday to credit for time served and three years of supervised release. Emerson was riding in an extra seat in the cockpit of a Horizon Air flight from Everett, Washington, to San Francisco and was subdued by the crew. The plane landed safely in Portland. Emerson pleaded guilty or no-contest to all charges against him in September as part of plea agreements with state and federal prosecutors. In the state case he was sentenced to five years of probation, among other measures.
