I shot this a few years ago when heading back to Hayward airport after shooting some aerial views of San Francisco. There isn't much to shoot in the last few minutes flying down Interstate 880, so I usually review what I've taken earlier in the shoot. I still keep an eye out for anything interesting out of the door as we are zipping along. A building roof grabbed my attention and you can see from the GoPro footage below I'm working really quickly. I see the roof, take a couple more shots, look around a bit more, snap a few quick aerials of downtown Oakland then get back to reviewing. I slowed down the video where I shot the graffiti as it was all over in a second or two. 

Turns out this is the work of two bay area graffiti artists, Swampy and GATS (Graffiti against the system). You can just about make out the BART line near the building, so this was probably the intended viewpoint, but I like how this looks shot on a long lens from 1000ft. This is the Instagram version of the original, I added a bit of tilt shift to emphasize the roof a bit more.
