YIKES!

Reports out today say that quite a bit of debris has been found in the South Indian Ocean off of Australia.

The WSJ reported this morning that besides the hourly pings from the engines, there was a final ping about eight minutes after the last hourly ping. The last ping was not a complete ping. Since the ping was not "scheduled" there had to be an event that triggered the ping, and since the ping was not completed, there was most likely a second event the prevented the transmission from finishing. The engineers would know what events would cause and unscheduled ping.

If the plane was nose dived into the ocean, I doubt there would be time for the engines to ping. It is possible the pilot ditched the plane in the ocean which might have allowed the engines enough time to start a ping. Most likely, the ping was sent due to an out of fuel condition and then the plane crashed. It would be interesting to know how long the ping takes to complete.

This just sounds more and more like a repeat of the Egyptian plane crash years ago.

i'm not familiar with that one.. explain? thanks

The Egyptian pilot committed suicide.

I think Dan is referring to EgyptAir Flight 990 - Wikipedia, the free encyclopedia.

One theory with the incomplete ping is that one engine ran out of fuel first and it's generators and electrical bus de-energized. The 777's control logic may have opened the breaker from the dead generator the closed a tie breaker to energize the dead bus from the other running engine's standby generator.
The Electronics and electrical systems on the re-energized bus were re-booting as the aircraft crashed.
Of course the obvious question. Who was sitting on top of this data and had no clue it was worth anything. Worse they would 't ask either. My brother worked on contract in Malaysia and Indonesia . Says he's not surprised as it's the way thier culture is.
Imagine looking for a debis field and sonar ping 3-4 days after the crash instead of 2-1/2 weeks later?

The information about the two possible paths has been known for quite some time. I really don't understand why the Aussies, and even the US, did not start looking to the west of Australia a long time ago since it was the most likely place the plane went too. If the debris is from the plane, and from the amount they appear to have found, it sounds like it is, they will now have to figure out how the winds, waves and currents moved the debris from where the plane crashed. Not impossible to do, but it would be easier if the debris have been found weeks ago.
