04/03/2006. Remarks by Christopher Nielsen. "This photo, taken by my grandfather and printed from a glass plate negative which no longer exists, shows my father, Knute Hans Nielsen at age 19. His hand rests on a common house downspout which was affixed to the exhaust of the OX5 of the "Jenny" to divert the fumes which gave him problems breathing. The photo was given to another barnstormer, Chestor Tectors, and this is a copy of it."
