BUILDER as a magazine to be reckoned with in the model hobby publishing business. In case you hadn’t noticed, and this is very possible, we have been named to that exclusive clique of "lim ited circu­ lation” publications by another member of the clique, which, by the way, is truly limited, in that it deals with only one phase of our great hobby. Because of this limited subject mat­ ter, and also because ot its apparent inability to find cover material which pertains directly to the hobby, we had discontinued regular reading o f this "model” magazine several years ago. However, in the last few days we have been receiving phone calls and letters from modeling friends who were quite disturbed about some statements by the editor, in the October issue of this magazine, pertaining to The MODEL "The day shift at Lockheed." Almost any time of the day, or night, this was the scene in the BUILDER. AMA hangar at Glenview Naval Air Station, north of Chicago, Illinois, during the Nationals.
