Fletcher was a multirated flight instructor, charter and corporate pilot and owner-operator of Mountain Aviation Services at Jackson Hole Airport.

Many will remember Fletcher as a great bear of a man and an intrepid soul. A devoted, loving family man and supportive friend, he also was, at various times in his life, an Olympic-caliber downriver kayaker, nationally ranked Nordic and Alpine skier and extreme sport filmmaker. He still holds the record for the fastest time in a kayak down the Grand Canyon - 49 hours. He was the author of numerous articles in aviation and kayak-related periodicals. He also was the author of Rivers of the Southwest and Flying the Mountains , the latter considered the definitive text for piloting single-engine aircraft in mountainous regions.
Fletcher and his family moved from Telluride, Colo., to Jackson Hole, Wyo. in the spring of 2004.
