I'm not aware that any of the recce aircraft have 'back flown' the calculated routes (plus current drift) to see if there are patches of increased debris density, but maybe they have. This one of the scenarios that I see inflight refuelling being useful for: 4h out to (say) southern extremity, 4-6h along path, then refuel to get home.
