Thanks training wheels who made the precise explanation for the accident. Some more details from the official briefing. The copilot is the flying pilot. The action of flight crew during the post-accident was praised although they did wrong inflight. Within 13 second the captain issued the first order to evacuate which was recorded clearly in the CVR, but cabin crew failed to get the order due to "the reason of equipment” (I don’t know what that mean). In 51st second the captain made the order again then the cabin crew guided all the passengers to exit the aircraft. Meanwhile the flight crew communicated with control tower. Within 3 minutes, first fire engine arrived in the site, following the first ambulance team within 5 minutes. Totally 8 emergency vehicles with team of 59 saved all life onboard. The captain was the last man to leave the aircraft. He made the double check to ensure that no one else was onboard.
