I have neither an interpretation nor a misinterpretation of length
contraction because length contraction is just an idiotic corollary of
Einstein's false light postulate. I am just trying to call the
attention to various aspects of the idiocy. For instance, I claim that
Harvey Brown CAN whereas Michel Janssen CANNOT explain how a long
train can be trapped inside a short tunnel:

or a 80m long pole can be trapped inside a 40m long barn:

http://www.math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html
"These are the props. You own a barn, 40m long, with automatic doors
at either end, that can be opened and closed simultaneously by a
switch. You also have a pole, 80m long, which of course won't fit in
the barn....So, as the pole passes through the barn, there is an
instant when it is completely within the barn. At that instant, you
close both doors simultaneously, with your switch. Of course, you open
them again pretty quickly, but at least momentarily you had the
contracted pole shut up in your barn."

But this does not mean that Harvey Brown's interpretation is less
idiotic than Michel Janssen's interpretation.
