What is William Lain Guthrie’s career?
William Lain Guthrie was a commercial airline pilot who became a celebrity after he was fired for refusing to dump spent jet fuel from his plane for environmental and safety grounds. He relocated his family to Miami after being hired as a pilot by Eastern Airlines.
On his 30th anniversary as an Eastern Airlines pilot, August 1, 1970, Captain Guthrie made international headlines by refusing to pour spent kerosene into the atmosphere, as was usual practice.
Instead, he stayed on the ground with his four-engine DC-8 and instructed the crew to drain the excess fuel from the previous flight before taking off.
The airline fired him two months later for insubordination, citing frequent and lengthy delays. Other pilots rallied around him, refusing to dump fuel as well, and the ensuing outcry pushed Eastern to reinstate him with full pay and the industry to stop aerial dumping. Captain Guthrie resigned soon after being reinstated.
His pilot’s license was suspended for 60 days in 1966 when he refused to allow a Federal Aviation Administration inspector into his cockpit for a regular inspection. He did so, he claimed, because the Civil Aeronautics Board declined to look into the Weather Bureau’s reporting processes. He said that federal aviation officials abandoned their responsibility to protect the public.
