Harry Gibson was a Peace Corps Fisheries Volunteer in Chile 1968-70.  When he returned to the US, he got a fisheries research position with the State of Idaho and authored several papers on freshwater fisheries.  While performing angler survey studies, he and the pilot of a small plane were unfortunately killed.  Harry was only 34 at the time, a sad ending to what would have been a promising career in freshwater fisheries research. 

Here is an article about Harry, from the Post-Register of Idaho Falls, Idaho, published in 1977:

IDAHO PAIR KILLED IN PLANE CRASH

Wednesday, July 6, 1977

PICABO, Idaho (AP) – Two Idaho men flying a research mission for the Idaho Fish and Game Department were killed when their plane crashed on a ranch southeast of here, Blaine County deputies said.

Deputy Donald Green identified the victims as the 47 year-old pilot, Faun Smith of Caldwell, and his lone passenger, Harry Gibson, 34, of Jerome.

He said they apparently died instantly when the single-engine plane crashed late Monday afternoon after a violent cloudburst in the Wood River Valley.

Fish and Game Department officials said the pair were making a research flight over Silver Creek when the plane went down.  Gibson, a senior fisheries research biologist, was making an angler survey to check fishing pressure along the creek, officials said.

The plane and pilot, under contract with the department from Clark’s Air Service, Inc., of Nampa, left the Nampa Airport about 3 p.m.

The wreckage was discovered about 5:30 p.m. with both occupants dead.

Green said there were no apparent witnesses to the crash, which occurred in a field belonging to rancher Frank McFloughlin.
