As someone who's tried most of those avenues, its currently not as easy as your said it. Currently working on my CFI. Lots people looking. Not enough jobs. As for the Cherokee 150 idea. I'm currently paying outa pocket for hours. It ain't cheap! I have 445 tt. Paying for 172 time and 15 hours of multi. to get my tt. up to 500/25.
I've actually been hearing A LOT about the possibility of age 68-70, more and more on the nets. From members of old on this board, that no longer post. And also on the nets. Due to stuff like what
