Other than being EXTREMELY argumentative about dumb sh!t and me needing to add another layer or three to my BS filter for a 4 day trip, not a whole lot in my opinion. I never really felt like I was doing to get violated or die, and he always found a way to get a jumpseater on to get home, but there was a massive personality change in the cockpit where CRM almost, and tact definitely, seemed to be foreign concepts and that's the primary difference between his disposition and mine.

Contrary to *most* FOs I talked to, I really didn't mind working with him; folks were known to call out sick or trip trade when paired with him...but the best way I can describe it is "He's a GREAT guy to fly with, when you aren't actually flying."
