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?
