I was intrigued by the full spoiler deployment (roll control) on the

It reminds me of Leeds/Bradford airport in a westerly gale that often
produced mountain wave rotor. Now landing in those conditions was
always FUN.

Metar Sea-Tac for mid afternoon Wednesday KSEA 282153Z 35008KT

shows no winds to give any cause for comment on either last Wednesday
(as the clip suggests) or even the Wednesday before. Strange.
