This is something I’ve realized only lately, that a lot of the things I like are capable of flight. About the same time I got into birdwatching, I also got into a hobby called planespotting. It’s basically observing aircraft and/or photographing them, and is often done at areas close to an airport. I didn’t get into it as much as I did in birdwatching, but I can differentiate Airbuses from Boeings at the very least.
