I'm not sure if the few remaining are flyable but I don't believe the Navy has a big interest in maintaining a flyable one for airshows (as much as I wish they would) because I'm sure it wouldn't be cheap. Plus there are a few other legendary US birds that occasionally show up at air shows P-51's, F-4U Corsairs, F-86's, F-4 Phantoms, etc. Unfortunately I seriously doubt US F-14's will ever take to the sky again
