Yep, they sure did but with one omission, changing the final way point (so as the track change flew directly over Erebus)"
And once again that was sloppy on the nav dept,
I’m not sure if any individuals within the Nav department were ever singled out but if the responsibility for the waypoint change not being relayed to the crew was ever layed at one persons feet, I think we’d find that they weren’t being paid 9x the national average wage. People are normally paid commensurate with the responsibility they carry on their shoulders.
