The front page of the June 12 1933 edition of the Toronto Daily Star included this photograph of the family of a Toronto pilot who appeared to be missing.
J. Erroll Boyd (1891-1960) was obviously not missing for long, as he lived for over 27 more years after this flight. In 1930, he had been the first Canadian to fly from Canada to England, earning him the nickname “The Lindbergh of England”. (Charles Lindbergh was the first pilot to fly from New York City to Paris non-stop, achieving this feat in 1927.)
I looked up J. Tower Boyd in the Toronto city directories. He does indeed appear in the 1933 directory at 121 Bedford Road. He has no listed occupation; presumably, he had retired. The last directory that he is listed in is 1940; the 1941 directory lists his widow.
By then, the younger Boyd had emigrated to the United States, becoming an American citizen on March 28, 1941. He was inducted into the Canadian Aviation Hall of Fame in 2017.
