Because of today's tragedy.Im still shocked.And its seems to me suspiscious.It sounds like a beginning of some political thriller book:In the place where in April 1940 Polish officers were murdered now all the top Polish officials are killed(President,top parlamentarists,chiefs of all armies,land,navy,air,and special forces).And considering the fact that Polish journalist who filmed the crash was arrested by Russians,it looks kind of suspiscious to me.Putin and Kaczynski had long history of disagreements,starting from Kaczynski's involvment in Georgia military conflict with Russia last year,and when Putin was in Poland Kaczynski offended him during his speech,and now Katyn,Putin didnt want Kaczynski to go there,Kaczynski forced this visit.Anyway they hated each other.Plane was kinda old-true,because none of the goverment wanted to be blamed by voters for spending during the economic crisis etc.etc.and goverment planes need special technical stuff inside-so it isnt so simple to replace it etc.etc.But it was only 2hour flight,it wasnt transatlantic 12hour flight,earlier Russian military plane supposedly was turned away from this airport.Its a military airport.Anyway i feel so sorry for the families.
