True, and let's not overlook that one piece may go straight down, while another may be attached to a structure with some buoyancy and therefore drift due to currents a considerate distance before it settles on the seabed.
Maybe someone who knows how the black box and CVR are attached to the airframe can shed some light on this possibility.
