Folks often confuse pods as being the same as one-structure triangles. When the 'object' is a pod, they typically maneuvor point first, whereas, one-structure triangles are known to exhibit no specific orientation, in fact the Stephenville triangle (I expended months studying the microwave tower interruption aspects of that event), the triangle was seen to tilt one of the points vertically, as one might take a slice of bread lying on a table, pivot on one corner of the slice, orienting the slice parallel with the wall of the room, and then, the triangle continued its forward motion, vertically, (same axis as a vertical stabilizer of a fixed wing aircraft) traveling over the court-house, in down-town Stephenville Texas. The triangles I saw, were all moving point forward, although I've also seen one triangle move blunt side. I suspect that geometry of the objects aren't predicated on aerodynamics. kronoz
