air support, I think you could paraphrase what everyone (or at least everyone who flys the line) is saying with: "Diversions are relatively infrequent, but when they do occur, for a half way competent crew, (which we'd like to think we all are!), they're usually a no sweat exercise."
The UA diversion into Brisbane certainly didn't rate the reports it was given in the Australian media.
Edited to add that I hadn't seen Keg's more than adequate reply saying more or less the same thing when I posted the message above.
