BBC's 10 theories on what happened to Malaysia plane

I like the theory as far as it goes, but I can’t figure out how to reconcile it with the satellite ping results, and the search arc derived from them. If the plane just kept flying west, it may well have passed over the Maldive islands (as some recent eyewitness reports apparently claim it did), but it shouldn’t have had enough fuel to reach the other edge of the known radius from the satellite (which I gather would be somewhere in Africa).

Anyone know enough about the satellite pings to meaningfully speculate on how they could be drastically wrong?
