J-Class, the warning is valid - some file even with broadband.
Very descriptive even though it was probably drilled into everybody to ever saw a King training VCR, but isn't it easy to under-estimate the consequences.
In various threads there are comments on and links to other previous wave, wake and vortex accidents. I think there is enough of a pattern over the loss of the vertical causing the engins to be bucked off, with the then inevitable consequences. If some of the more analytically and technically minded wanted to research.
Of course it is still conjecture and speculation at this time - but the investigators are good at finding all the needles in the haystack. Lets hope we can at least learn from the wreck. RIP
