CRM
There are a few ******** non CRM guys on the bus, all the 767 guys are laid back and ask for an input. On the bus, guy is flying .80, bumpy as hell, I spin it back to .76 or .78 whatever the turb speed is on bus. You should have seen his face.
Another tried to fly through a red cell on the radar, yep, I just call ATC and say I have lightening 12 o'clock, need a vector.
If you have a concern you need to say something to get it on the recorder, then take whatever action is necessary.
