The ceo of airasia was a bit more cautious in a tweet. If right part of tail section then the black box should be there.

So plane came across, smoke coming out of it and saw the plane, the parachuters jumping out and then heard a big bang like, yeah, it blew up. It blew up before it hit the water. Reporter the plane nosedived crashing into the waters as hundreds of stunned holiday onlookers watched. The pilot, what happened to him . He landed down there. He landed in there pretty deep so had to wait for fire brigade to come down and cut him out. Reporter some of the survivors managed to swim to the coast. While others were rescued by boat. You can see the plane here just below the surface. Authorities will lift the plane today and are investigating the cause. The group paid to tandem sky dive with skydive taupo as seen here. The pilot was experienced but had only been with the company a few days. His fastthinking action is credited with saving all aboard. They had to jump at a high altitude.
