(Thursday, August 25, 1966, 1:40 p.m. PDT) — The Beatles landed at Seattle-Tacoma International Airport today on the 12th stop of the British rock band’s 14-stop third (and what would turn out to be last) North American tour.

This monumental day marked two major milestones in rock history: the Fab Four’s final official joint press conference and the absolute last time they would ever pull double duty by performing two shows in a single day.

The Beatles had secretly agreed to stop touring after Monday’s tour finale at Candlestick Park in San Francisco, amid mounting safety concerns, unbearable live sound conditions, and an overwhelming desire to focus on their increasingly complex studio recordings.
