Gilbert Broadcasts

In the eighth in the Harvard-WRUL series on "The Fight for a Free World," Horace N. Gilbert, visiting lecturer on Business Administration, will speak tonight on the ability of the United States to produce planes, "the principal weapon of war."

In discussing the problem, Professor Gilbert will treat the obstacles we have met in designing our fighting planes, about which we have had no practical experience. He feels that we have had especial difficulties in designing pursuit planes, for which he considers our first plans very poor.
