I'm looking for some help finding a tail number on an Alaska flight. Living in Crystal City by DCA, I see quite an array of planes and special liveries. I've been lucky to recently get pics of both the "Starliner 75" and "Spirit of Seattle". Today, I saw another special one and I "think" is was Alaska, but it was too late to see clearly. I believe it was flight AS 771 as all the rest during that time were US, so my goal is to be able to figure out when it will back to DCA. Unfortunately, my normal methods aren't showing the tail number:

I appreciate any help. Thanks!
