They found debris very quickly from the AF jet, specifically the tail section. The challenge here is not to find the plane, but just to find ANY debris. 4 days of having a “clue” from two separate coordinates by satellite of what looks to be the same object has still netted no, zip, zero results even when they knew where to look for this “debris”.
It’s been two weeks and some since it disappeared. They were relatively “Johnny on the spot” with 447 and had sightings in a couple of days. There won’t be any obvious floating debris fields from it now if there ever were any to begin with. Whatever was left has been dispersed and sent in any number of directions or succumbed to the waves.
