Why not this?
It seems really odd that in an age where nearly every street in Britain is monitored by CCTV the runways on an airport as busy as this are not. I've watched this thread and its associated (poor) news coverage since the start. In particular the crap graphical cartoon representations of "what might have happened" offend.
Surely for the cost of two hard drive (security style, say three hour) video recorders and two cameras almost buried in the ground using long (telephoto) lenses at each end of the runway, we'd be able to see something of what really did occur?
Such a low cost solution to early answers ...............tell me where I'm going wrong?
