FDNY Jet Plane

The department doesn't own that jet. They have nothing to do with that jet. That is a regular JetBlue airliner in scheduled passenger service. JetBlue decided to paint this one in an FDNY-related scheme. That's all. Painting it in some FDNY-related scheme does not transfer the plane to the FDNY. I can buy an FDNY logo baseball cap from any kitschy souvenir shop in New York. That doesn't make me a member of the FDNY. This is the same thing, writ large - the FDNY logo on the tail is just the paintjob, and has no other significance. The plane had already been with JetBlue for 8 years as a regular A320, and continues to be with JetBlue, still flying normal routes.

Seriously, I'm not sure how this thread grew so long without everyone realizing this. Airlines frequently do this sort of thing. They'll paint airliners in oneoff schemes. US Airways has an A320 painted with a Philadelphia Eagles livery, but with the "US Airways" on the fuselage where it normally goes. That plane does not belong to the Eagles, nor do they fly in it (link about it) - it has the scheme because US Airways decided "hey, we advertise with the Eagles, let's paint a plane with their livery".
