Getting beat up by the Air Force as a pilot for the last 7 years, and 5 years before that as a Flying Crew Chief is much worse than anything Atlas can throw at me. At least, the guys I work with who fly for Atlas say, anyway. LOL! The lifestyle will be just fine. Especially since they actually give you a schedule, in black and white, on paper. And that's what you work.
My worry is the knowledge part. I've never operated a plane where I had to look up an FAR, and I've seen a Jepp approach like twice. I have no idea exactly what questions I missed on the test, so this leads to me being worried that I won't get hired because I look like an idiot when it comes to FAA knowledge.
