I have one more word for this prophecy chapter. That is the simple reminder that the startling developments people like are only possible through wide-spread labor in many fields. The ex-war pilot was right. Even a new discovery is just fitting in, in the jig-saw puzzle of scientific achievement, an unusually large piece. Many little curley-kews are needed around it to make its meaning clear. All kinds of minds in all kinds of schools and laboratories, or alone in cubby-holes, are trying to work out theoretical details of efficient flight. Helping them are those who put the theories to practical use. That women will share in these endeavors, even more than they have in the past, is my wish—and prophecy.
