Why do older planes not have a middle hand luggage compartment?
Since the L-1011 was born prior to airlines charging for checked baggage, and passengers didn’t feel the need to bring massive carry-on items with them, the L-1011 featured compact overhead bins that were (to quote advertising of the day) “sized for a lady’s wig box.”
