Then why was one of the 3 zip lines found to be down after the crash? Sure, something departed the scene, you can see it falling (perhaps a FLIR head or rescue hoist or night-sun?). But if you fly into a wire it's quite possible the helicopter is not going to be intact after that.
With the severity of the impact and resulting fire I'd be surprised if there was anything of the FDR/CVR left.
