Both flight recorders have been found at the plane crash site near Aktau, Kazakhstan, where an Azerbaijani airliner carrying 67 people crashed on Wednesday, killing at least 38, according to Kazakh authorities. Kazakhstan, Azerbaijan, Brazil, and other relevant parties are conducting a joint investigation into the plane crash, while two main questions have been raised regarding the crash. The aircraft had reportedly deviated hundreds of kilometers off course, and many small holes are visible on the plane in pictures from the crash site.
