I haven't read the accident report on the Subic Bay accident, which would give the full story but, just reading the last post, I still think that, despite the extremely unfortunate outcome (which must have taken a lot of justification to management!), they still made the right decision. By taking the fast ASI for landing, they risked landing fast which, in the worst case, merely meant that they ran off the end. If they'd decided to believe the slow ASI, instead of running off the end, they could have finished up half a mile short of the runway, upside down, spinning in, as a result of a stall.
On balance, they got it right (unless there were other clues)!
