Of course it was in free-fall, Pat. What else would it be? ;-)

It will be slowed by the atmosphere till it reaches terminal velocity.
Maybe if it was odd shaped enough it might start gliding sideways to
some extent as it descended, but I can't picture it doing that well
enough to come flying through a window into a room


Unless it
hit something outside and then bounced through the window, I suspect
that somebody threw it through the window.


I suspect it came in at an angle because it entered the atmosphere at an
angle, and that it may well have clipped a tree nearby.


Something that low in weight would lose all of its latent horizontal
velocity long before impact. Any horizontal velocity would have to be
due to some aerodynamic effect on it as it fell at its terminal
velocity, and although I can picture it coming down in a spiral of some
sort, as it spun on its axis (in fact that would be very likely one
would think, unless it was a perfect disc, sphere, teardrop, or some
other smooth and symmetrical aerodynamic form) I don't think its going
to come down at a angle that let it build up any significant horizontal
velocity unless it grew a vertical fin to keep it straight and gliding
in one direction.
Now if it hit something and bounced off before going through the window,
that would make sense.
If it hit a inclined surface at high speed (like a tree's inclined
trunk), that could slow it and get it going sideways both at once.
There's a good photo of it he

Here's another shot, showing its size and that it's basically disc
shaped: http://www.fox28.com/Images/030707meteor.jpg
