I still don't see how those forces could cause this particular object to stop for a few seconds and then change direction.

Actually I believe there is plenty of doubt that these are UFOs. In fact I think this is an example of what happens when people view things that are outside of their day to day experience. There are very few people with first hand experience with on-orbit activities nevermind microgravity operations and effects. I am not one who has such experience in any way but I have been a professional astronomer for years prior to starting my own business, and had to learn much about zero-g operations as relates to orbital mechanics, drag etc...

My first thoughts on this video are that this is indeed space debris, most likely ice. Ice particles can be found floating around the shuttle and launched satellites. Just because we leave the very very moist atmosphere doesnt mean that the moisture just goes away. It freezes and flakes off.

This brings up another issue. The ice coating has something else within. Trapped air. These small bubbles are in the ice and as Carbon Dioxide "dry" ice sizzles and pops here on the Earth under 14.7 lbs per sq Inch, in space in micro-pressure and microgravity, these water ice particles also sizzle and sublimate, releasing the trapped air as the ice sublimates away little by little. As it is released, it acts like a small jet and PHSSTTT!!! Off in one direction it goes, and yes this can be a 90 or 180 degree turn. Why? Because in the micro-pressure environment of space, you also have microgravity. That jet can act on the ice particle in a big big way. THIS is what you see when you see particles moving in many different directions seemingly under control of something. That something is the trapped air being released catastrophically as the particles sublimate.

You cannot ignore the science and call something a UFO and say something like "there is no doubt these are UFOs". That is irresponsible and leads to junk science which as we have seen, can get us into major trouble!
