Authorities investigate possible plane crash in their search for Andrew Carnegie's nephew and namesake.

April 19, 1938: Authorities investigate if 28-year-old Andrew Carnegie Whitfield, nephew and namesake of Andrew Carnegie, who had disappeared days earlier, may have crashed his small plane into Long Island Sound. A house painter working near the sound said he heard a small plane and, by the sound of its motor, it was in trouble. Whitfield, a newlywed, had been about to move to Bethlehem, Pennsylvania, for a job promotion when he told family he would be back "in a few minutes" and disappeared. Some reported he had flown his plane from a local airfield. His fate remains a mystery.
