Even later, he became quite anti-technology. He enthusiastically participated in ecological and humanist causes: endangered tribal minorities, whales, eagles, rainforests. Lindbergh flew to the jungles of Africa, South America, Phillipines, etc. to work personally on these projects.
However, in his introductory chapter to the 1970-published "Wartime Journals," Lindbergh asserted that he still held the same pre-war beliefs, with no word of criticism for the Nazi government. He insisted that the war was wrong, and that the wrong government had been fought: Communist Russia was the real enemy. He even denied that the cause of the Allies had triumphed.
Lindbergh continued his work on humanist projects. He never learned to dance. The bold, gifted, outspoken pioneer died of cancer in Maui in 1974, facing crashing sea, vast sky, and brilliant sun.
