 One historian wrote, Jeschonnek did not have the judgement necessary for his post.Jeschonnek experienced the difficulty in level-bombing with KG 152 and with Ernst Udet, became a strong advocate of the dive-bomber.Jeschonnek's support of Udet's idea to add dive-bombing capability to all conventional bomber aircraft delayed and retarded the development and production of promising level-bomber designs damaging the German war effort.
