Seems like the Commission's investigation is going well.....

The commission’s crisis of credibility deepened when one of its leading experts, Jacek Ronda, an engineering professor specialising in underwater welding, admitted that he had lied on national television about a crucial piece of evidence supporting the explosion theory. During an interview, he said he had a Russian document proving that the Polish airliner had not descended below 100m.
“There was nothing on that document – it was a bluff,” Mr Ronda admitted in a later radio interview, explaining he had tried to fool the television journalist because he did not want to weaken the case for an explosion in public.
The blunders continued. Last month, Gazeta Wyborcza newspaper obtained records of conversations by commission members with Poland’s military prosecutor's office quizzing them about their expertise in plane crash investigations, as well as how they supported the theory that the airliner was blown up.
One of the experts, whose name was blacked out in the testimony, admitted that his expertise stemmed in part from gluing together model aircraft, as well as sitting in the cockpit of a fighter jet during an air show. He added he often observed the working of airliner wings while peering out of the window as a passenger.
None of the experts had visited the site of the crash. They based their conclusions on photographs and the internet.
Finally, Wieslaw Binienda, a professor of Polish origin working in the US, was accused of using a manipulated photograph of the wing of the destroyed airliner. He was trying to prove his thesis that it was damaged by a bomb and not by hitting trees in the landing attempt. Mr Binienda denies this.
