Captain Collins and First Officer Cassin were briefed on a flight path that took the aircraft over the ice-covered waters of McMurdo Sound well to the west of Mt. Erebus but were issued, for use in the aircraft's computer, as the nav track a flight path which went directly over Mt. Erebus itself, without the aircrew being told of the change, involved admissions of a whole succession of inexcusable blunders by individual members of the executive staff.
The absolute root of this disaster!
My seven year old son can comprehend this what else seems to be the problem?
