I was ground assualting a very large UFO, I can't remember what type.  There
was one Sectopod on it, on the upper level.  I knew this because three
soldiers had walked out of a door to a death by plasma.  I got really
annoyed at this(all three were captain or above), so I got my two men on the
lower level to fire at the roof square where I thought it was with heavy
plasmas.  The ceiling gave way and the body of a Sectopod fell to the bottom
level.  When I sent more men up to the top level, there were still a pair of
Sectopod legs standing over a hole in the ceiling.
  Has this happened to anyone else?
