The Batwing (or Batplane) is Batman's aircraft and main mode of aerial transportation. Batman used the Batwing when he needed to travel long distances to counter airborne threats, or to ambush enemies from above.
Batman flew that Batwing to Claw Island to stop Two-Face and The Riddler. When he got close to Claw Island, the Riddler fired a high-powered laser at the Batwing, and caused it to crash into the Harbor. Batman ejected the wings, and piloted the Batwing in its Batsub mode. Batman ejected himself from the Batsub and fought Riddler's Frogmen to save Robin.
