Folks,
I can remember one better than this, back in Ansett days. Loaded the wrong passengers on the aircraft. The problem became apparent somewhere over centrals southern NSW, when the Captain gave the time of arrival etc. for Adelaide, more or less together, 102 finger hit the call button, the Brisbane passengers.
And yes, the Adelaide self loading freight was somewhere a bit north of WLM by the time the message got through. And, yes again, this was before any routine PA announcement, just before closing the doors, saying where aeroplane was going -- which appeared in the cabin SOPs very shortly after.
The poor bastard who was the T/O responsible, an old mate, never lived it down, because we didn't let him.
The TAA mob couldn't manage to stop laughing for day.
Tootle pip!!
