Abrial A-12 Bagoas
 The A-12 was a highly unusual experimental glider designed by Georges Abrial in the early 1930s. Not only was the design tailless but it featured wings of extremely small aspect ratio (1:6) - short and stubby unlike the usually long and slender wings of a sailplane. After encouraging tests of models in the wind tunnel at St Cyr Abrial built a full-sized version.
