Regarding MH370 floating wreckage, if any, the following is from The Australian filed on Jan 6th 2014. "AN eight-metre boat believed lost eight months ago after being capsized by a freak wave off Exmouth Western Australia has been found 4000 nautical miles away, washed up on an island (Mayotte) off the coast of Madagascar."
Doing some maths that works out at approx 0.7kts drift.
MH370 was "lost" on 8th March, it is now 10th April say 33 days ago.
I estimate wreckage has drifted 550Nm and dispersed over a vast area. No doubt some may well end up in Mayotte in due course!
