MH370 speculation after flight wreckage washes up on Reunion Island, page-91

Jindalee is dream-time stuff and can't find anything smaller than an iron/aluminium ship [can't help monitor wooden non-conventional arrivals] and needs to be focussed. You look for ships OR you look for other things.

It's a big world and you need a REASON to search a small section of it's surface. They don't casually look at aircraft the way I look at flightradar24.
