This is so true, and I feel needs to be quoted just for emphasis.
Like, when I "made it" to the brass ring job that I had wanted for years... I got sick after 9 months on the job and couldn't fly anymore. Not saying that's common, but the insecurity of the career is just, so unbelievably high and difficult to parse as someone living through it. A buddy of mine called me up around 2009 or so while he was flying in the bush. "Dude, I just did a 747 captains IOE in the 207." Apparently this dude had worked at Hageland many years ago, then got on at Tradewinds. When he got furloughed he went back to one of the only jobs available...
It's a great job, but I don't think many people realize how nerve-wracking being a pilot is when you're not even in the freaking airplane.
