Welcome to the Virtual 4th Fighter Group on Warbirds online Air Combat simulation. You’ll find information on all aspects of the 4th. You can contact the 4th, to join our squad or just ask questions about the 4th or Warbirds itself. The 4th is not only a great group of pilots but a lot of fun to fly with.
