Finding floating surface debris and locating the wreckage at depth are two separate and disparate events.

Agreed. They found surface debris from Air France 447 five days after it went down.

No surface debris would point towards the aircraft having gone in largely intact, with an enclosed fuselage. An explosion in flight would have to be pretty significant to destroy seat cushions or other items that would float.

Is this aircraft largely composite materials that would blow to bits unlike a metal skinned aircraft? So many questions!
