NASA proposed a policy for the jettison of trash from the ISS space station.
This article notes that a recent ISS space station spacewalk by Russian cosmonauts involved one man jettisoning by hand a replaced electronics pack. The pack was shoved by arm and hand downwards to Earth. See the link to a YouTube video showing the dramatic toss.
How much time and distance does that package take to fall before disintegrating/burning-up?
Also: Is the point of burning-up too far to see the flare by camera from the space station?
