The accident rate of the F-104 was rather high, especially in GAF service where it acquired the moniker 'Widowmaker'. Many of the problems could be overcome by better training of the pilots, understandable as they were flying a plane with almost no wing. Of the 158 examples built of the two-seat, training TF-104G version 104 were operated by the GAF. Fortunately one of these is now preserved at the Luftwaffenmuseum at Gatow.
