Short Sunderland overflying the Dover Patrol monument at St. Margarets at Cliffe, east of Dover. The Dover Patrol Monuments are a trio of war memorials designed by Sir Aston Webb to commemorate the Royal Navy's Dover Patrol of the First World War. Two identical granite memorial obelisks, 75 feet (23 m) high, were erected near Dover and on the Cap Blanc-Nez near Calais in 1921 and 1922. The third obelisk is in New York.
