Update on the Sriwijaya Air 737-500 crash. The SAR and Navy team already got the signal from the Plane Black Box. On local media, the Navy divers told that the condition of the plane is scattered. Shown that it impact the water on relative high speed. Reminiscent of Lion Air MAX crash also in the area not far from present crash site.
Both of the plane are loosing altitude fast. This one losing 3000+ feet in one minute from 10000+ feet, before reach 250+ feet in another minute plus. All happen so fast, that the ATC inquiry on why they are loosing altitude and going west from flight plan, has not been answered by the Pilots, before the contact lost.
Video frm CNN Indonesia shown how the Navy Divers scavenging the wreck pieces. If there's good side on this search, the water depth in the area is only around 15-25 meter.
Too soon to speculate, however loosing the altitude so fast while steering west from the flight path, and the pilots has not even have time to answered ATC inquiries. All shown in my opinion something catastrophic happens on flight control.
