Yup.

The comment you refer to is typical of those who have only seen one side of the fence...or who feel the need to buff up their self-image.

That kind of comment really makes me chuckle. When I was doing Captain upgrade line instruction, the absolute worst student I ever had was this retired USAF B-52 pilot and former squadron commander (a position he seemed to never tire in reminding me of). If managing a crew in all of its complexity was supposed to build better CRM skills, this guy missed the boat a long time ago.

Other than that, to answer the original question...previous experience in this regard counts for little to nothing. I often was asked as a new hire what I thought about the differences between an airline cockpit and fighters. My thinking then and now is that it all depends on the individual's personality. Some fit in well, some don't...just like others from different backgrounds.
