The Boeing company had previously established Seattle as a center for
aircraft manufacturing, but following the oil crisis and a costly debacle over the Boeing 747, the company suffered and many were forced to
leave the area in search of alternative work.
This could entail examining the plane or helicopter before they can
leave the
manufacturing plant, diagnosing major electrical problems on the
aircraft, using tools to remove any defective parts, and ensuring that commercial
aircraft meet government or state regulations before flying with passengers.
