The second black box has been found at the plane crash site near Aktau and handed over to the investigation department, according to a Kazakh official from transport department on Thursday. The Embraer 190 aircraft operated by Azerbaijan Airlines flight J2-8243 from Baku to Grozny crashed near Aktau Airport in Kazakhstan on Wednesday.

Mobile phone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball. Some of the videos posted on social media showed survivors dragging fellow passengers away from the wreckage.

Officials say an Azerbaijani airliner has crashed in the Kazakhstani city of Aktau with Kazakhstan’s Emergency Ministry now saying that at least 28 people survived the crash, which could mean that over 30 people are likely dead.
