(Portland, OR) -- The off-duty Alaska Airlines pilot accused of trying to crash a plane carrying more than 80 people in October is pleading not guilty. Forty-four-year-old Joseph David Emerson appeared in court yesterday, where he was arraigned on 83 counts of recklessly endangering another person and one count of endangering an aircraft. A judge ruled that Emerson can be released from jail pending trial and set bail at 50-thousand dollars. The release conditions include that Emerson undergo mental health services, stay away from drugs and alcohol and not come within 30 feet of an operable aircraft. The release terms also allow him to return to his home in California while awaiting trial. Emerson was riding in the cockpit jump seat on a flight from Everett to San Francisco when he allegedly tried to shut down the jet's engines by activating the fire suppression system to cut off fuel to the engines.
