This sub-series consists of research material related to the work William Kuzyk did in relation to the CF-105 Arrow fighter jet. Included within this sub-series are reports, notes, articles, data, graphs, sketches related to various technical aspects of the aircraft. There is a notebook of William Kuzyk's, containing notes on issues relating to supersonic and hypersonic speed, about characteristics of vertical take-off and landing, and observations relating to a UFO sighting in 1958. There are also reports about the various versions of the Arrow, including long-range version and a zero-length launch (or vertical take-off and landing) version. There are two technical drawings of what appears to be the first design of the Arrow, dating from 1955; and a large technical drawing of a design for a zero-length launch Arrow, dating from 1958.
