I've been an aviation enthusiast for decades, and have been a heavy user of flight simulator software on my computer through those years, but I'm not a pilot. I did take flying lessons in Cessnas and Cherokees, but found it to be scary, and I realized that I'm not going to be an actual pilot. I just love the technology and would like to be proficient in operating a 737, even if it's just theoretical. My real background is in software and engineering. I'm financially independent and have the time and resources to pursue a serious full-time hobby. I was wondering: What is the farthest I can go in acquiring qualifications for operating a 737, that does not involve actual flying? Could I, for example, enroll in a real 737 training school and do all the required simulator time and checks and exams as real pilots do, to gain a qualification (even knowing that I cannot *use* the qualification for anything except buying more simulator time)? This could be compared to a person who is interested in medicine and who has no need or intention of having a career in medicine gaining a medical degree out of pure curiosity.
