The plot thickens. Although the Malaysian government still officially denies it, it seems that signals from the plane WERE being received long after it disappeared from radar screens. Confident enough that the US government is repositioning Navy ships in the Indian Ocean.

The WSJ article initially mentioned signals sent by the Rolls Royce engines, but apparently that was incorrect. Instead, the onboard ACARS system continued to ping a satellite for four to five hours although ACARS had apparently been turned off, too. The pinging is an automatic function that occurs even when the system is turned off and more detailed signals are no longer being relayed to the satellite.

Wow, what is going on here?
