Dear Rob,

I might make some error of thought (and please note that I am very happy
with your trajectory angle reconstructions! That is good work that helps to
crack the case!), but I do not quite follow your argument about the angles
(which might however be my mind putting me off only). To me, it is clear
that with a trail to the west of Porthcawl, Pencoed which is even more to
the east should see it at a flatter angle. Hold a ruler next to the left of
your head to mimic the trail as seen in the Porthcawl image. Then move your
head to the right while keep looking at the ruler. You'll note that the
angle becomes less steep.

PS: I really do not see how this could have been a fireball, as much as I
would want. Maybe DOD data can change my mind. After this evening , I will
drop out of the discussion by the way, as I have to prepare myself for
defending my PhD dissertation for a committee of peers next thursday.
