Task: Question Generation
Input (English): In 1936, Wever was killed in an air crash. The failure to implement his vision for the new Luftwaffe was largely attributable to his immediate successors. Ex-Army personnel Albert Kesselring and Hans-Jürgen Stumpff are usually blamed for the turning away from strategic planning and focusing on close air support. However, it would seem the two most prominent enthusiasts for the focus on ground-support operations (direct or indirect) were actually Hugo Sperrle and Hans Jeschonnek. These men were long-time professional airmen involved in German air services since early in their careers. The Luftwaffe was not pressured into ground support operations because of pressure from the army, or because it was led by ex-army personnel. It was instead a mission that suited the Luftwaffe's existing approach to warfare; a culture of joint inter-service operations, rather than independent strategic air campaigns.
Output (English): How did Wever die?
