Video of the final seconds of the flight of the KingAir 350 has come to light from two aspects, It appears clearly that the outer wing sections have separated in flight. Vapour coming from both sides of the foreshortened wings is likely fuel escaping from the tanks outboard of the engine. One report indicates the accident occurred at a time of heavy local rain.
refer to video from ANCNEWS at time 1:02/2:58, and 1:51-1:53/2:58
Take care out there, a good many thunderstorms will challenge the structure of aircraft either directly or from the consequences of loss of control and recovery.
Hopefully this will be investigated promptly and causation will come to light, but losing wings in flight symmetrically comes from a handful of causes.
