DRAFT TRANSLATION

The question appearing is, why nothing is said about such danger in any official reports? For myself I am answering as follows: because there is no such danger. The figure 5000km - is reality, it is related to the entry-angle 0,6°, the Progress generates the necessary 40 m/sec. of the impulse. The reports on the decrease of the ascent-height are intentional de-information in order to hide the fact of remaining possibility to ascent the station from the public. For the benefit of this reason the following argument can be adduced. The statements are distributed that the increase of the fuel-usage (from 16% up to 60%) was resulted by a failure of girodines. Firstly, girodines are serviceable but switched off. Secondly, girodines could never counteract the moment occurring by racing of an unbalanced station. Thirdly, girodin is not non-basis propulsive device, it can collect the moment of impulse, but then it needs to be reset by spending the fuel saved previously.

It turns out, that in the situation of the station the public repeatedly collided with  deliberate de-information.  The following three statements are all incorrect: 1) that Mir is in a bad condition; 2) That Mir cannot be elevated safely 3) that de-orbiting is safe. All this provokes  this it directs on sad thoughts about the future of the branch and the destiny of the station. No one analyzes the situation and looks for ways of its saving. For the benefit of such opinion is also the fact that the braking impulse is generating earlier then the moment when the station reaches the optimal height of its generation. Induces on suspicions the close character of the information about the condition of the station, the nature of the additionally appeared losses and the notorious plan of three-impulse-de-orbitation. The author, employee of  CAGI, despite of his insisting requests, did not succeed to get access to this information.
