Bob, there you go again.  We don't attempt to measure lumber flying
past us with a rigid rod or anything else for that matter.  It's
usually best to just 'duck'.  The point was (re-read Einstein's paper
SLOWLY) was that both ends of the rigid rod move at the SAME time (not
approximately so).  If you combine this self-contradictory idea with
the weird notion of light as a real object that ALWAYS travels at the
same speed then the Lorentz transform is inevitable.
