I only have this picture of a model
>The XB-19 project was intended to test flight characteristics and design techniques for giant bombers. Despite advances in technology that made the XB-19 obsolete before it was completed, the Army Air Corps felt that the prototype would be useful for testing despite Douglas Aircraft wanting to cancel the expensive project.[citation needed] Its construction took so long that competition for the contracts to make the XB-35 and XB-36 occurred two months before its first flight.
