Plus, talk to the people. They really have no idea what's going on behind the scenes at all. If it's gone absolutely pear-shaped, tell 'em!
Seriously! Personally, if I'm sitting on a blistering aircraft in the middle of summer for an hour and my only respite is buying a $2 coke once we're finally in the air, all that wonderment of the crew not killing me, traveling at 500 mph and landing on a narrow piece of runway thousands of miles away isn't going to amount to a hill of beans.
Worst comes to worst, we've gone from near anarchy to everyone thinking we're the shiznit just with a craftily-worded PA.
I dunno, that's just how I roll.
