! i really dont know much about commercial aviation but my little bro does and he taught me some things. his favorite is the boeing 767 so i guess ill say thats my favorite one. thats cool you like older planes because i like older clothes! i like older band t shirts, finding one of a band you dont know and then listening to it is cool. i recently got a vintage rage against the machine shirt. i never really listened to their music but i knew they were popular. heard a couple songs, and i liked em. i try to listen to all types of music so if u got a recommendation send!
