  We revisit our investigation of the claim of [1] that old black holes contain
a firewall, i.e. an in-falling observer encounters highly excited states at a
time much shorter than the light crossing time of the Schwarzschild radius. We
used the formalism of Holographic Space-time (HST) where there is no dramatic
change in particle physics inside the horizon until a time of order the
Schwarzschild radius. We correct our description of the interior of the black
hole . HST provides a complete description of the quantum mechanics along any
time-like trajectory, even those which fall through the black hole horizon. The
latter are described as alternative factorizations of the description of an
external observer, turning the mirage of the interior provided by that
observer's membrane paradigm on the stretched horizon, into reality.
