LONDON.- Tate Britain today unveils its new Duveens Commission, Harrier and Jaguar, by Fiona Banner. Banners largest work to date, Harrier and Jaguar brings the highly-charged physicality of two real fighter jets, both previously in active military service, into the unexpected setting of the neoclassical Duveen Galleries. Harrier and Jaguar has been specially devised for the Tate Britain Duveens Commission 2010, supported by Sotheby’s. In the South Duveens, a Sea Harrier jet is suspended vertically, its bulk spanning floor to ceiling, wall to wall. Mimicking its namesake the harrier hawk, the aircraft’s surface has been reworked with handpainted graphic feather markings – the cockpit, the eyes, the nose cone, the beak – and hung nose pointing towards the floor, bringing to mind a trussed bird. In the North Duveens, a Sepecat Jaguar lies belly-up on the floor, its elegant, elongated body traces the length the gallery. Strip
