Interesting that the US dispatched a ship with towed array to the search area in the last few days.
Re information NOT being released in real time, not surprising and if you think of the criticisms the Malaysians endured by releasing info and then retracting it, I would say that the US, UK, Aust etc are being very careful. The only people who need to know are the families and the searchers, everyone else - especially the media - can wait.
At least Aust has lots of activity to keep the media busy and occupied.
