Hasn't anyone noticed that the
real reason for this mishap hasn't been brought up? The PIC was
texting his wife, on final approach!!
It's interesting to note that one European pax reported in some detail that the aircraft went through "the heaviest rainstorm he had ever encountered in an aircraft, 2 to 3 minutes of solid rain", just prior to the ditching.
Anyone who has ever had any extensive experience with weather, knows full well - particularly in the tropics - that it is entirely possible to have clear sky and full sun, and little wind where you're located - yet only 2 or 3 miles away, you can have a violent thunderstorm raging, with strong wind gusts and heavy rain.
