In a few months I will begin training as a firefighter. I figured
that becoming a pilot would be a great second career. I haven't taken
any schooling for my pilots license and am just curious if anyone has
any advice they can give me?

For instance: Is it profitable? Is it very difficult to get a loan
for a plane? How long does it take to become a pilot of a six to
eight passenger plane? If I'm using the plane for personal use, is
the gas consumption for a multi engine incredibly high?

Thanks for any advice.
