One more thought. I once flew back home on a BA flight and the Captain very kindly invited me into the cockpit for the approach and landing. Buckled up at FL360 and asked the engineer when he wanted me to keep my mouth shut for the sterile cockpit.
"Sterile Cockpit. . . Sterile Cockpit. . . uh, that is not a term we use in British aviation" he scoffed.
They then flew the rest of the approach profile blabbing about this, that and the other until they touched down. After October's documentry would'nt be surprised if they were hammered too!
Guys as they say in FAA land: if you're gonna talk the talk you gotta walk the walk.
Think I'll be flying Delta next time!
