I do too and I have done a lot of study and coursework on the subject. It can be challenging, but studying and discussing aerospace topics makes professional and personal life more rewarding. I design aircraft systems for a living and enjoy talking about, studying, flying, and designing airplanes. Aircraft are sufficiently complex now that one can spend a lifetime on them without exhausting the subject. Airplanes are objects of practicality, beauty, science, symbolism, history, and are a key component in the advancement of a nation. One of the first things to obtain funding when a nation tries to move forward or protect its assets is aircraft. As such, they are one of the more interesting things to spend time on if you ask me.
