Ethiopia's transport minister says flight data from last week's crash of a Boeing 737 Max 8 aircraft had "clear similarities" with last October's crash in Indonesia involving the same model.<br />Dagmawit Moges told reporters that all relevant data from the black boxes have been recovered and a preliminary report would be released within 30 days.<br />He did not provide details on what those similarities were, but said they would be subject to further investigation. <br />Both flights crashed just minutes take off and reports have suggested a new automated anti-stalling system may be the cause of both accidents. <br />The system apparently forced the planes to nosedive soon after engaging autopilot. <br />
