FYI This is already kind of outdated, as new info is coming so fast,
I don't have time to translate the whole article, so just an excerpt
for people who believe the planes were shot down from the ground. M.L.
All theories - in the "black box"
By Vladimir Demchenko, Roman Kirillov
Theory No 1. Terrorist act
Theory No 2. Technical malfunction and human mistake
Theory No 3. Total nonsense: attack from the ground.
This third theory, the representatives of authorities call a total
nonsens [polny bred], nevertheless on some aviation forums on the
Internet it has already been actively discussed. Origin of this and
others improbable nonsensical theories are explained most of all by
the fact that our citizens suspect that the authorities hide
something and withhold an announcement of certain essential
information. So, that's how this is born.
So here, according to these nonsensical theories those aircrafts were
down by the Russian air defense forces [PVO], after an information
was received that one or two planes have been hijacked. The
supporters of this theory assume that after 11 September of 2001 in
many countries relevant instructions were put in place, intended not
to allow for the repetition of that tragedy. These loose cannons
assume that a certain "strong-arm [volevoye resheniye]" decision was
made and enshrined into some secret order: to bring down a hijacked
aircraft before terrorists have time to direct them toward strategic
targets. In the case of the Sochi-bound plane, such objects, purely
theoretically, could be two: - Volga-Don AES [Volgodonsk Nuclear
Power Station] and president Putin, who was vacationing at that time
on the Black Sea coast. However, there are no serious actual
confirmation of such assumptions even on the Internet.
- This theory, that the aircrafts were downed, that's utter stupidity
[chistoi vody glupost], stated to Izvestia one of the experts on the
air defense. - We now hear a lot of these theories. Someone today
even said that the aircraft was brought down by the Belorussian PVO -
which was conducting a firing exercise on the Ashaluk firing range in
Astrakhan province [oblast]. Allegedly, as it was with that Tu-154
shot down by Ukraine. That's complete rubbish! In order to bring down
any aircraft, an order "from the top" is needed. And they bring down
only the airplanes that violate the airspace and which pose a threat
to the state. Place yourself at the place of commander of battalion,
on the battle station alert. Would you carry out the order to bring
down a plane, knowing that the target - is a passenger airplane?
that's not very likely. Now let's imagine: one aircraft shot down in
Rostov, the other one - in Tula. For this you must already have
minimum two battalion commanders. Furthermore, if a missile is
launched, then the radars (let me add - also the foreign spy
satellites as this was in the case with Ukraine then) for sure will
detect it. In this case, no missiles were seen on radars.
