Karel X, are you saying that, at the very end of the overshoot area, the aircraft was still only on its nose gear, with the main gear in the air? Does this match with the exit/collision speed of 170kph Kulverstuka's post mentions?
No, I described situation at the final section of the RWY, just before overshooting. When crossing end of RWY, the speed was 220kph. After overshoot, the plane reportedly sat on all three gears and automatically begun a breaking action.
Early in this forum, there are videos of last landing at Pardubice airport. OK, it is little hard (nose wheel "bang"), but it should not be the reason for conflicting or uncooperative atmosphere in the cockpit several hours later. Now it looks like cockpit crew discussion about this irrelevant mistake was the first link in the chain of following fate events.
