Pictured over Chesapeake Bay, most likely by the 104th Observation Squadron of the Maryland National Guard on 17 November 1937 according to the photo source. The service from Bermuda - not from Britain - to New York was redirected to Baltimore Municipal Airport between this date and 6 April 1938 to avoid the icy winter conditions in New York. The next winter the service continued to New York, until Cavalier ditched and sank in the ocean on 21 January 1939. Photo from: Enoch Pratt Free Library

The S.23 flying boats lacked the range to cross the big pond with payload but a limited route was opened between the British territory of Bermuda and New York or Baltimore. Cavalier was actually shipped to Bermuda. Suffering icing, the aircraft ditched en route from NY - Port Washington to Bermuda on 21 January 1939 and three of the 13 people on board lost their lives.
