Corporate jets are rarely painted in interesting schemes so, when they are, you notice them. This one showed at at Boeing Field with a puma on the tail. A bit of research when back home suggests it is a project between Jay Z and the sport gear manufacturer Puma. I think it is to help out athletes that are sponsored by them. The registration is apparently a reference to Jay Z himself. I have no idea who was on it on this occasion. Maybe Sean was onboard?
