Tailless Aircraft Bibliography Edition 1-g

     Edition 1-f, which is sold out, contained over 5600 annotated tailless aircraft and related listings: reports, papers, books, articles, patents, etc. of 1867 - present, listed chronologically and supported by introductory material, 3 Appendices, and other helpful information.  Historical overview.  Information on sources, location and acquisition of material.  Alphabetical listing of 370 creators of tailless and related aircraft, including dates and configurations.  More. Only a limited number printed. Not cross referenced:  342 pages.  It was spiral bound in plain black vinyl.  By far the largest ever of its kind - a unique source of hardcore information. 
     But don't despair, Edition 1-g is in the works and will be bigger and better than ever. It will also include a very extensive listing of the relevant U.S. patents, which may be the most comprehensive one ever put together.  A publication date has not been set yet, so check back here once in a while.
