On 19 May 2016, fire broke out on board an Airbus A320 en-route to Cairo at night. The fire spread rapidly from the forward area of the aircraft and rapidly intensified. Loss of control due to conditions on the flight deck resulted in descent and sea impact with all 66 occupants killed. Work for the Investigation (reproduced in the final report) which identified a leak from the flight crew emergency oxygen system as the fire source was eventually discounted and it was concluded that the origin was activation of explosive materials in the forward galley just behind the flight deck.
