John, a turn to the right at 20:31:35 is what the radar data shows and is consistent with the debris field. It IS quite probable that it did in fact occur as the aircraft had lost its left wing and apparently went into a sharp spiraling dive.
The turn to the right is a matter of the right wing forcing the plane to yaw 90 degrees to the left and with the resulting dive ended up veering sharply downwards and 110 degrees to the right of its former bearing.
And again, that's what the radar and debris shows...
