On Aug 30th 2016 Egypt's CAA announced that a delegation from Russia has arrived in Egypt to meet with their counterparts of Egypt and Germany in order to prepare a meeting at a secure location at Cairo Airport, where all wreckage of the aircraft have been taken to. The meeting is to determine the initial point of where the fuselage started to disintegrate. Representatives from Ireland, France and the United States (representing the the countries of design, manufacture of aircraft and engines) plus an expert from Airbus are going to attend that meeting, too.
