Exotic aspects of black holes: an astronaut near the horizon (on the methodological note by A A Grib and Yu V Pavlov "Is it possible to see the infinite future of the Universe when falling into a black hole?")

We comment on the methodological note by A A Grib and Yu V Pavlov [Phys. Usp. 52 257 (2009)] to show that its authors are incorrect in understanding a passage that they quote from A M Cherepashchuk’s book Black holes in the Universe (Fryazino: Vek-2, 2005, p. 7) and which supposes an astronaut to be at rest in the vicinity of the horizon (not to fall freely into a black hole). With this error corrected, Grib and Pavlov’s note is quite useful methodologically.
