All we know is that the aircraft vanished from radar and no radio communication was received.
We have a very approximate location involving thousands of square miles of sea and it could take a long time for the first debris to be seen. If the aircraft met the water in one piece this will narrow down the search area, If the aircraft broke up in flight the main wreckage including the flight recorders could be a hundred miles from a piece of lightweight debris.
Sadly the reality is that the flight recorders are unlikely to be recovered for a long time, weeks or even months.
Until then all speculation is pointless.
