You don't need high speed or a tight turn when there is black ice and it seems the taxyway was supposed to be closed but still lighted and not mentioned as closed on ATIS or by the ATC who gave the taxi clearance (other taxyways were deiced but not the stretch in question)
It seems the following a/c was warned by the tower (after the incident). Firefighters could hardly stand up when they went to assist. No notam or atis warning at the time though shortly *after* a car tested braking action on the Polderbaan and it was broadcast as only medium.
there but for the grace of God indeed .....
