Angus Houston says;
Pings are heard twice more on Tuesday. Analysis of the previous pings have confirmed that they are from man made device and consistent with the expected FDR/CVR pingger. This included the 1.1sec delay in the pings. They are still going ahead with trying out TPL to get more data. The time to launch the unmanned sub with side scan sonar is undecided.
So overall it seems another small but important step closer to locating MH370. Lets hope there is some conclusion soon to the families.
