Here is an observation of something a bit different.
When you throw a fairly large styrofoam glider (over four feet wingspan), with the wings level and into a steady wind over smooth ground, it seems to always turn away from the wind, and I can not figure it out. These were launched at about chest-height. With no wind, these will fly fairly straight. Do they throw frisbees in the UK? These will always bank to one side if you throw them at a high angle.
It is not clear to me why this happens to such a glider, when launched in a level attitude (there are no moveable control surfaces), with the fuselage parallel with the ground. I've never seen one stay pointed into the wind.
