OLYMPIA, Wash. -- The Washington Department of Transportation has suspended the air search for a missing Lake Roesiger pilot who has been missing since Oct. 10.

Gordon Last, 51, was last seen flying his Taylorcraft two-seat airplane when he departed from Harvey Field Airport in Snohomish. He was expected to return to Harvey Field later that afternoon. His girlfriend reported him as missing when he failed to return.

Searching since Oct. 11, rescue teams flew for a total of about 250 hours and about 175 personnel participated in the search. Two helicopters from King and Snohomish counties also aided in the air search.

Due to witness and radar information, search teams focused on the area between Shelton and Westport. The area is about 1,900 square miles covering Grays Harbor County, the southeast corner of Thurston County and a small piece of northwest Lewis County, said WSDOT.

According to reports, the plane had no emergency locator beacon or transponder on board, and no flight plan was filed.

Anyone who may have information on this aircraft is still encouraged to contact the search staff at missingaircraft@wsdot.wa.gov or 360-410-0461.
