Note
Grunau Baby CF-ZBH was one of four "war prize" gliders, each allocated by the National Research Council, to a Canadian soaring club. For an excellent article on those four gliders, including ZBH, please see the article by Lloyd Bungey at https://www.wgc.mb.ca/static/freeflight/89_04.pdfNote
A condition for allocation of the "war prize" gliders was that they be used for aeronautical research on behalf of the Canadian National Research Council. ZBH was used as the platform for evaluation of several types of angle of attack indicator. The results of that research were published in the SAC 1948/49 Year Book, which is included in this archive under SAC Publications, at page 68
