Assuming that they are landing into wind, and not down wind, a light head wind combined with a quick stop would be the "ideal" situation to get into vortex ring state, wouldn't you agree?
No Sorry I wouldn't But that is beside the point. Previous posters had it listed as possible vrs. And I know that vrs sounds bad and scarey but usually when you are close to the ground and you spear in and spread the skids it's lack of power, or too big of a demand on power too late... not vrs
Maybe my experience is biased because I operate mainly in high temperatures (32-45 C) but I regularly have pucker experiences with not enough power but have never had a problem with vrs.
And I am a long way from a perfect pilot but my second point was that if I was 63 and I had a private licence and I was taking my old mate who is 75 out for a poke around in a 22 one of the things I wouldn't be showing him is a quick stop !!!
