They'll find it TOR is my best wild ass guess. The Med looks to be fairly deep approximately where 804 disappeared, so recovery of the CVR/FDR could possibly take some time.
I'm not speculating any more than officials at Egyptair, but I find it intriguing that it disappeared off radar right slap bang in the middle of that part of the Med - between Crete (north west) and Cyprus (north east) and Turkey (north) and Egypt to the south.
