  We study the observation of a thin dust shell, radially freely falling to a
Reissner-Nordstrom black hole, by an observer who is also freely and radially
falling into this black hole. Considered and resolved are several common
paradoxes and fallacies peculiar for such problems. The results of this
analytical study are written as a numerical code that allows for calculating
all related effects of this model. The numerical result have been presented in
a few synthesized videos, making a colorful, quantitative and detailed
description of the occurring astrophysical phenomena, both above and below the
horizon.
