Jim Jabczenski, son of Mitchell Jabczenski, sent in some pics from the family’s scrap book of his father’s and grandfather’s hydroplanes that they campaigned in the 1950s to 60s. Bud James is also mentioned (my father’s mechanic) and drove F-89 sometimes. The Vintage Hydroplanes has stories of both boats authored by Phil Kunz: Chiro III F-89 and Chiro-Too F-93. Both of these boats have a very unique history and are a worthwhile read.
