ch4 had more science
The vortexing / scouring
the seismometer traces
the apparently pre-existing cracks in the meteoritic material
the radient heat ,reported by observers , leading to zeroing-in on
ground-fall material

half of the BBC effort was repeat and then all that extraneous musak as well
to make up for it, S@N seems to have adopted my choice of lead presenter ,
from the thread here , april last year
