Faulty equipment and poor communication by Russian ground staff contributed to a plane crash last year that killed Poland's president and 95 others, a Polish government commission investigating the disaster said today.
Its long-awaited report, drawn up by a panel of experts over 15 months, also said many of the Polish air crew lacked appropriate training for the flight and some equipment on board their TU-154 Tupolev was not properly prepared.
President Lech Kaczynski, his wife Maria, many senior officials and top military staff died in the crash as their plane was trying to land on April 10, 2010, in thick fog near the western Russian city of Smolensk.
"The commission has established that the lighting systems at the [Smolensk] airport were faulty and inadequate," commission member Lieut Col Robert Benedict told a news conference.
The Russian side gave wrong orders to the plane's pilots, who he said were making only a trial descent rather than seriously attempting to land when the crash happened after miscalculating their distance from the ground.
The Polish delegation had been heading to the nearby Katyn forest to commemorate the 70th anniversary of the murder of Polish officers by Soviet secret police during the second World War.
The commission had some sharp criticism for the Polish side, saying that the pilot lacked experience in landing aircraft in adverse weather conditions. He was also the only Russian-speaking crew member, which meant he had to deal directly with the ground staff in addition to flying the plane.
Equipment on board the plane had not been properly prepared, another member of the commission, Wieslaw Jedynak, told the news conference.
However, the report said there was no evidence that Mr Kaczynski or other passengers had put pressure on the pilots to land against their wishes. Some media and politicians have suggested the pilots had tried to land the plane under duress.
Polish defence minister Bogdan Klich resigned today after the report catalogued serious errors by the crew of the military plane. "He offered his resignation yesterday, and I accepted it today," Prime Minister Donald Tusk told a news conference after the publication of the report.
In its own report into the disaster, published in January, Russia put all the blame for the disaster on the Polish crew, infuriating the Polish side which said conditions at Smolensk airport had also been a contributing factor.
The shock of the crash initially helped to accelerate a cautious diplomatic rapprochement between Moscow and Warsaw, long in dispute over various issues, but the Russian report complicated bilateral relations.
Mr Kaczynski's identical twin brother Jaroslaw, who heads Poland's main opposition party, has accused Mr Tusk's centrist government of conniving with Moscow to cover up the full truth of the Smolensk disaster. Mr Tusk, who is tipped to win re-election in October, strongly denies the claims.
