I don't think there is much in the SAR equipment in that hemisphere so getting the crews and such there may take days before they could mount a proper search they have one P3 and 20 Hercs in Brazil but I fear that might be beyond their capabilities , another thing to ponder is if their ATC system has improved since the Legacy/GOL midairwhatever (lightning, electrical, structural, bomb) - it was a sudden and complete catastrophic failure with not even a peep from the flight crew.
maybe they will find some seat cushions or even a fuel cell
