It is a beautiful Aircraft alright, only one very BIG problem. For every hour it flies it needs 15 hours of maintance,so they do not fly much. It has never lived up to the design specs that Boeing said it would have,including speed,payload and range.And the Airforce is terrified to use it in combat because it is SO fragile and not as stealthy as we have been lead to believe,its like the old japanese zero. One well placed shot from anything and its going down.
