Thanks for that MM43 - always informative.
Do you happen to have any information on the deep sea currents in that area, i.e. would they generally follow the surface currents ?
Why do I ask...well I suspect the wreckage went down very slowly due to buoyancy in its construction and trapped fuel, indeed if they do find it I suspect it will be miles from the point of impact. Not good news for the current search but it might be an interesting exercise to try and calculate where it might be say, 24 hours after contact with the surface.
