The Deekay Aircraft Corp. Ltd. was formed in 1937 to build aircraft using a new type of wing constrution developed by mr S.C. Hart-Still.
The first machine incorporating this form of wing is the Deekay "Knight" two seat cabin monoplane,the wings of this aircraft are in wood, but developments are in hand for the use of plastic materials and as experience is gained with the plastic construction so its use will be extended
to the production aircraft of the company. (From Jane's All Aircraft of the World - 1938 )
