And that is the exact problem, the aircraft is only monitored or pinged either on demand or at regular intervals. If it were tracked continuously the present needle in a haystack situation would not have arisen. It defies belief that a plane loaded with electronics in this day and age is not continuously tracked. I bet that changes though it didn't after the last one went down in the water which surprises me though I think they knew roughly where that was at the time of crashing. They have just this afternoon (Australian time) decided to ramp up the search in Australia's S&R zone and Australia is to be in charge of this. In reality they haven't got a clue and are clutching at anything that sounds good.
