This topic is precisely why I left commercial flying for Bell, and Bell for TC - security and stability. In my commercial career, I saw too many 60-odd year old pilots zooming around in a 206 or 350, trying to make a living from contract to contract with no retirement date in sight. I decided that wouldn't be me.
The vast majority of us have no other marketable skill, as Deuce said. If you want to use your aviation background, you can move to TC, consult, or take any of a small number of marketing jobs out there. Slim pickin's indeed.
For me, I took courses and tried to get other work skills, and started a small business. Oh yeah, and found a much younger woman who makes more than me... 😀
Hey Mini - I sent you a PM
