From Wikipedia above;
The German modified Starfighters were especially problematic, due to the modifed version's alarming accident rate. In German service alone, 292 of the 916 Starfighters crashed, claiming the lives of 115 pilots, leading to cries that the Starfighter was fundamentally unsafe and earning it the Widowmaker nickname, among others (see below). However, the non-German F-104 proved much safer and earned a better track record.
