(B) When Charles Lindbergh was attempting his solo transatlantic flight, being very reluctant to have any extra weight on his plane, he => Incorrect
(C) Since he was very reluctant to carry any extra weight on his plane when he was attempting his solo transatlantic flight, so Charles Lindbergh => Wordy
(D) Being very reluctant to carry any extra weight on his plane when he attempted his solo transatlantic flight was the reason that Charles Lindbergh => he and his do not refer to Charls
(E) Very reluctant to have any extra weight on his plane when he attempted his solo transatlantic flight, Charles Lindbergh => Correct.. Correctly modifies Charls Lindberg in the underlined sentence as well as clause following it
