The data reporting system, they believe, was shut down at 1:07 a.m. The transponder
— which transmits location and altitude — shut down at 1:21 a.m.

I’m not an aviation expert but the above to me could mean that some event other than manual
shut down by a pilot could the cause of the differing times.

The following gives an indication that the plane was aloft way beyond the shut down of the
data reporting systems. Thus it could be some type of hijacking. But where is the plane now?

.....but senior administration officials told ABC News the missing Malaysian flight
continued to “ping” a satellite on an hourly basis after it lost contact with radar.....

Thanks for posting the article.

You can turn off a transponder with it’s individual control switch, with it’s circuit breaker, with the avionics master switch or a failure of the system. There are two independent transponder systems on board. Total electrical failure is such a remote possibility that it is not even on the B777 emergency checklist.
