It's been a while since I've read the transcript, but it seems like towards the end there wasn't that much chit chat. Overall, my impression was that they were discussing the same things all pilots discuss. Did they violate sterile cockpit? Sure. Just like the rest of us have. We have all seen it on our own aircraft, as well as jumping on other aircraft. Feds and check airmen, also. Regional and major. The real issue is the lack of airmanship.
