We are getting the Russian version of events, a version which asserts pilot error. This is followed by commentary on psychology and a swipe at Kaczynski.
For whatever it may be worth, another version coming out of Poland is that (1) the Russians wanted the plane to divert to another airfield and the pilot said it was not possible because of mechanical difficulties, and (2) the Russian built plane (Tupolev) had been overhauled in Russia a couple of months ago.
Bottom line: jump to no conclusions and wait for a full and objective investigation.
Overhauled in Russia, says it all.
Most Freepers normally do the exact opposite.
