Hexagon side of any hexagon, then the midpoints of the segments connecting the centroids of opposite triangles form another equilateral triangle. A skew hexagon is a skew polygon with 6 vertices and edges but not existing on the same plane. The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes. A regular skew hexagon is vertex-transitive with equal edge lengths. In 3-dimensions it will be a zig-zag skew hexagon and can be seen in the vertices and side edges of a triangular antiprism with the same D, [2,6] symmetry, order
A Plane Is Born on the Europa's wings and Mark puts his composite skills to the test. In part 2, he continues his flight training as he learns about climbing and descending. Nigel Marshall and Rob Cooper talk about the Pitenphol Air-camper they built at work in their lunch-hours. - You Have Control! Work on the plane continues with the Cockpit module and control yokes. Mark also receives a visit from Neville Eyre, his PFA inspector who checks to see that his work so far is air worthy. Over at Staverton Airport, it's pass the sick bag when he is introduced to "stalling". Finally,
