Wassmer WA 26 Squale
The WA 28 Espadon (or Swordfish) high performance single-seater is the all-glassfibre version of the earlier WA 26 Squale (or Shark), differing from it in having cantilever shoulder wings of the same span, area, aspect ratio and plan form but of glassfibre/plastic foam sandwich construction instead of the WA 26 Squale's conventional wooden construction with trailing edge air brakes inboard of the ailerons;
