I could write a book about flight school management dynamics. The personalities, the hopefuls, the dreamers, the wild power dynamics between a flight school and a student who desperately wants to get to the airlines (the promise land). The instructors, who all were just recently students now grinding out hours to qualify for an airline job. Safety. Studying and learning. Relationships. Accidents.
The financial aspects are incredibly risky for many. The statistics: only 22% of students who begin training for the first step - a private pilot license - end up finishing. For those wanting to make a career or progress further, there's your instrument rating (to fly in bad weather), your commercial license (to fly for money), your flight instructor license (so you can teach - which essentially is your only path to gaining experience/hours without having to pay for it out of pocket), and then your Air Transport license, which ... airlines. That requires 1500 hours of experience.
It truly was one of the more fascinating adventures I've done.
