With all due respect, gums did not request that it not be discussed at all, and rather than open up a new thread on a topic that has been discussed many times before, I elected to summarize what I knew here as briefly as I could.
In this case the FMS did not have two waypoints programmed in with the same designator (as gums said), but caused a partial entry to bring up a list which was sorted in alphabetical order - a feature which crews of the time were not trained on. I explicitly stated that the initial error was in the map supplied to the crew, and not the responsibility of the crew themselves.
I've lost friends to accidents and worse, so I'd never knowingly be disrespectful of anyone who'd gone through the same, but in this case there was a factual error in the telling which needed to be explained.
Apologies if I caused any grief or offence.
