'Preliminary analysis' of Ukraine jetliner's black boxes complete

An international investigation team has completed a preliminary analysis of data from the black boxes of a Ukrainian passenger plane mistakenly shot down by Iran in January, the Transportation Safety Board of Canada said Thursday. "The download and preliminary data analysis was an important milestone in what must be a thorough and transparent safety investigation," said TSB chair Katy Fox, without providing details on the results of the analysis. "The work in Paris is finished, but the investigation is far from over. There are still many key questions that need to be answered," she said. "We have urged Iran to release factual information from the recorders as soon as possible," Fox said, adding that Iran -- which is leading the investigation -- has not authorized the TSB to release details. A team of investigators from the same countries as the victims of the plane crash met this week at France's Bureau for Enquiry and Analysis for Civil Aviation Safety (BEA), in Paris, to begin extracting the data. On Monday, the BEA announced data from the black boxes had been successfully downloaded.<br/>
