The White Knight was designed in 1963 while Posnansky was a student in Switzerland, but later has been substantially modified. It has a faired fixed landing gear and speed limiting dive brakes on both upper and lower surfaces, a center of gravity tow hook and a side-mounted control stick. The ship’s similarity in looks to the Swiss FFA Diamant is evident: it was designed during the same period when the predecessor to the Diamant was under development in Switzerland, and while that aircraft first flew with Schleicher Ka-6 wings, the White Knight used Schleicher Ka-8 wings.
