That is awesome Doug! I can relate as I am working toward similar side hustle gigs. Music has been great but I really enjoy the challenge of flying new aircraft I can't or won't afford for myself. Got some right seat in a CJ3+ this year. Mostly as the pilot monitoring but got to be the pilot flying on 4 legs. Flew the new Vision Jet too. Old dogs can learn new tricks.
All the best in your new adventures
