Hi To all: I worked under the guidance, as a mechanic, of Ollie in the late 70s early 80s on the North Slope for western. He was the type of guy that had photo graphic memory. We could talk to him via short wave radio while he was in Anchorage. We would have a major problem and most of the time he would help us get it going. He had just a knack for how things worked.  Mark Hoffert ND USA
