Smolensk - accident or assassination?

The initial reasoning doesn’t allow me to debar any version of this tragic event, so I can’t debar also the option of an accident and I can’t rule out the assassination, a planned action -as the media-. Media seem to target only the version of the accident, and the so-called warning against drawing hasty conclusions. So what? Don’t even put the question of whether the disaster couldn’t be planned the action? Maybe the question bother somebody? It offends someone? If not, it certainly offends common sense. But sense don’t afraid to question and as someone pointed out rightly, there are no stupid questions, may be only stupid answers. In this case, less of wisdom and folly* - important, that the answers are true.
Not assuming for a moment version of the accident, let's see if would be someone, who rejoice with this tragedy?

Can it be useful to anyone for anything immediate disappearance from public life several dozen group of people deciding on key issues Polish - defense, financial policy, national memory, etc.? Who could have in this business? Polish people, Polish patriots, or perhaps those to whom the existence of Polish bother?

If they want eliminate from the political life of large amounts of people uncomfortable at the same time, located at the same time on a small area, away from the possibility of quickly provide effective relief, whether it would be best not to do it in an aircraft?
Is it normal that the plane that crashed was under Russian control of the technical and passed the last review in Samara (Russia)? Is the safety of heads of state, Polish political elites should be at the time of stay in the air in the hands of Russian technicians?

Whether Russian special services, if they want, would have the technical ability to share organizing attacks, or may not be able to do something like this, to plan and execute? In which territory would be easier to organize such an action, only to fully control it (avoid the press, placing a land militia, not to grant interviews, etc.) - for another, or on your own?
If somebody wants to cripple, incapacitate an organized community, the State, which group will be eliminate first, the social? Ordinary gray citizens who may, at most, to vote in elections once every few years or maybe those who every day take many decisions, which determine the fate of the whole community? And who, during the Second World War the Germans and the Soviets murdered and deported to concentration camps in the first place, or sometimes not officers, professors, clergy, people in power? Are not those his authority, in word and attitude have an impact on the entire nation, would be able to pull it towards independence? If I want to kill somebody, then cut his arm, heel, or maybe your head? Has anyone heard of the so-called cutting of heads of the nation (Germany did it in Auschwitz, Dachau, Stutthof, and the Soviets at Katyn, Kharkov, Mednove etc.)?

I think it wasn’t the case. First you need to ask yourself:
For what kind of Kaczynski hasn’t been invited on the same day as the Tusk? Why Putin wanted to split them?

It certainly wasn’t the case. How is it possible that the pilot, 2km from the airport was at the height of the trees!? It was the fog (and it's not so big), Polish plane full of VIPs.... and someone took advantage of the opportunity. Pilot landed just as he gave to the airport. Apparently, the light from the runway where set in the woods. The stories of witnesses shows that the pilot trying to pick up yet. So when he was low enough to see, that it wasn’t the airport (gave wrong parameters) tried to salvage the situation. Unfortunately ... I also heard from witness, that he heard two explosions - one lesser, second greater-could also be the case that the pilot realized that there isn’t the landing and try to escape, but the Russians shot yet down because it would be stupidity releasing them) And now all deal with the Russian service nobody commit to the scene. Isn’t it strange? They have a “black box” and they can do what they want. And probably it will be the pilot foult, because he can’t no longer defend himself... not the man who advise him.

I think it was attempt, why they don’t let the Polish jurnalists immediatly after the split. Why they put gun to jurnalists head, why nobody speak about it no longer, why similar threads are removed from the forums? I wasn’t supporter of L. Kaczynski, but he was patriot, who spoke the truth about Russia, and took a penalty, for which was he awarded in Georgia as a national hero! International news talked about the accident based on the Russian media and knowing, that the investigation is also Russian. Russia depends on the fact that the mob thought it was an accident, and Poland is too weak to say anything or accuse Russia.

As for me, too much cases here.
