1971: Will the Last Person Leaving SEATTLE — Turn Out the Lights
I’d argue the 757, 767 and 737 Classic (i.e. -300 to -500), all of which much more 80s than 70s were much more glorious.
And the 90s brought us the 737NG and 777 which continue to carry more than everything else today and for that matter anything else ever, other than maybe the A320ceo.
I would say even the 787 is a good plane, if it didn't have major build quality issues because of Boeing wanting to reduce manufacturing costs (it was initially built at two plants, Everett WA and North Charleston SC, and it got to a point when airlines only wanted to have 787s manufactured in Everett, but ultimately the production in Everett was discontinued). And now the same major build quality issues start popping up with the 737 MAX (whose fuselage is being manufactured by Spirit Aerosystems, which was originally a division of Boeing but was outsourced in 2005).
I'm just a casual follower but it seems their glory days are from the 60s and 70s and they've been coasting along since then.
