A group of four flying boats take off for a tour of the Baltic region.
Full title reads: "Calshot. 'Showing the (Royal Air Force) Flag' 4 of our mighty flying boats leave for tour of Baltic sea ports."
Pan along line of four flying boats (currently with wheels on) as they sit on the concrete in front of aircraft hangers. The planes are being prepared for their long flight.
The RAF Planes are moved out onto the water and slowly make their way up to take off speed.
We see the planes flying off to the Baltic in formation.
