Editing Moon Hoax (section)

===Stanislav Pokrovsky===
Dr '''Stanislav Georgievich Pokrovsky''' (b. 1959)<ref>S. Pokrovsky, [http://vif2ne.ru/nvz/forum/archive/210/210419 Intermediate bottom line], 10/9/07 (Rus.)</ref> is a Russian candidate of technical sciences and General Director of the scientific-manufacturing enterprise "Project-D-MSK".<ref name="Pokrovsky">[http://professionali.ru/~170677 Pokrovsky], Professionali.ru (Rus.)</ref>

In 2007, he studied the filmed staging of the first stage (S-IC) of the Saturn V rocket after the launch of Apollo 11.<ref>[http://archive.org/details/HSF-mov-apollo11_launchclip03 A view of the first stage separation of Apollo 11], The Internet archive</ref> Analysing it frame by frame, he calculated the actual speed of the Saturn V rocket at S-IC staging time using four different, independent and mutually verifying methods. With all of them, the calculated speed turned out to be at maximum half (1.2 km/s) of the declared one at that point (2.4 km/s). He concluded that due to this, no more than 28 t could be brought on the way to the Moon, including the spacecraft, instead of the 46 t declared by NASA, and so a loop around the Moon was possible but not a manned landing on the Moon with return to the Earth.<ref>S.

In 2008, Pokrovsky also claimed to have determined the reason why a higher speed was impossible—problems with the Inconel X-750 superalloy used for the tubes of the wall of the thrust chamber of the F-1 engine,<ref>[http://history.nasa.gov/SP-4206/ch4.htm "Stages to Saturn", Chapter 4], R. Bilstein, 22/3/02</ref> whose physics of high-temperature strength was not yet studied at that time. The strength of the material changes when affected by high temperature and plastic deformations. As a result, the F-1 engine thrust had to be lowered by at least 20%. With these assumptions, he calculated that the real speed would be the same as he had already estimated (see above). Pokrovsky proved that six or more F-1 engines (instead of five) could not be used due to the increased fuel mass required by each new engine, which in turn would require more engines, and so on.<ref name="Moon"/><ref name="moreExact"/><ref>Proceedings of the conference at the Russian New University, Nano-technologies section, 25/4/08 (Rus.)</ref><ref>S.

Pokrovsky claims that his Saturn V speed estimation is the "first direct proof of the impossibility of the Apollo Moon landing".<ref name="Pokrovsky"/> He says that fifteen specialists with scientific degrees (e.g. Alexander Budnik)<ref>[http://science-kaluga.ru/authors?content=info&id=57 Alexander Budnik], Institute for physics and power engineering (Rus.)</ref> who reviewed his paper, of which at least five aerodynamics experts and three narrow specialists in ultrasonic movement and aerosols, raised no objections in principle, and the specific wishes and notes they (e.g. Vladimir Surdin)<ref>[http://lnfm1.sai.msu.ru/~surdin Vladimir Surdin], Sternberg Astronomical Institute</ref> did have could not change his results significantly even if followed.<ref>S.

Two days after adding the above text about Pokrovsky's findings there on 23 July 2009, the entire article was proposed for deletion and [http://wikipedia.org/wiki/Apollo_Moon_landing_hoax_accusers deleted] in a week.
