The lay-out of the window was conceived and planned by Air-Vice-Marshal C.E. Chilton, C.B., C.B.E., Senior Air Staff Officer at Headquarters Coastal Command, while the detailed design work and construction of the window was carried out by Aircraftman Norman R. Attwood, a National Serviceman on the staff of Headquarters Coastal Command. It was cut and glazed by Messrs. William Morris and Company of Westminster, and the stonework was by the Croft Granite Company.
In the centre of the window stands the figure of a typical Coastal Command aircrew - pilots, navigators, signallers, radar operators, flight engineers or gunners all looked much the same although of many nationalities: Polish, Czechoslovakian, Dutch, Norwegian and United States squadrons joined forces in the maritime air battle in close and friendly partnership with the Australian, New Zealand, Canadian, South African and United Kingdom squadrons of Coastal Command.
They fought together as a band of brothers and had the same determination to seek out and destroy the enemy wherever he was to be found.
This particular aircrew symbolises their everyday task; he is dressed in his normal flying kit and is flashing his Aldis lamp the recognition signal of the day to the nearest corvette or destroyer guarding the convoy to be joined.
No signal was so welcome to those who sailed in the convoyed ships and the majority of threatened convoys were met day or night, irrespective of weather, throughout the war.
The central figure stands upon a pile of the weapons used in the anti-U-boat and anti-enemy shipping war - the depth charge, the torpedo and the bomb being the most prominent.
Below this are the convoys which were - in conjunction with the ships of the Royal and Allied Navies - the aircrews' daily task to guard and here can be seen the signs of enemy activity and our counter-attacks.
In this lower part of the window is symbolised the hardest fought victory during which the men at sea and in the air fought with their various craft, the weapons, the fuel and the many scientific devices and instruments designed, fashioned or produced by the thousands of anonymous men and women working behind the scenes in many different countries.
It also symbolises the work of those who planned and directed the war at sea and co-ordinated the allied effort.
Above and beyond the central figure are two hands clasping the Royal Navy and Royal Air Force ensigns, typifying the marriage of these two great services for their triple task of finding the enemy, striking the enemy and protecting our ships.
Behind and framing the ensigns and dominating all the top of the window is the sun at dawn as seen by those thousands of aircrew who flew against the enemy over the vast expanse of sea of some ten million square miles and this will symbolise to many the relief felt by those upon the sea and in the air that another day had started and with God's help our ships were a day nearer safety.
The badges of the subordinate formations of Coastal Command adorn the sides of the window, while the Command badge is in the place of honour at the top. Those formations without badges are shown at the base of the window below the words "Constant Endeavour" - the Coastal Command motto: never were such words so well chosen.
On either side of the motto the Blue and Red Ensigns are included to remind us of the heroic endurance of the Royal Fleet Auxiliary, the Merchant Navy and the fishing fleets. The badges of the Royal Air Force and the Royal Navy flank the main window in the adjacent top side panels, thus completing the picture.
