IN 2010 the nation will celebrate one of the most iconic moments in modern history - the Battle of Britain. In the summer of 1940 Britain stood completely alone.

Had the brave aircrew of the RAF lost the battle, the world might still be a very different place today. Britain would have been occupied, there would have been no D-Day and perhaps more significantly, the Nazis would have been free to develop the first atomic bomb.

They might still have been masters of Europe to this day.

Seventy years on we tend to forget how important a debt we owe to the aircrew of the RAF and Commonwealth and foreign nationals who came to help and who Winston Churchill called "The Few".

A best-selling author and film-maker is currently working on a landmark and definitive project to celebrate this very important anniversary. He would like to hear from anybody who had a personal involvement with the Battle of Britain.

You may not have been a pilot, but you might have been a ground crew member of a squadron, or worked on an airfield or in a sector station.

You may have been involved in Radio Direction Finding, the Royal Observer Corps, searchlights, ack-ack guns, or barrage balloons.

You may have worked in a factory making Spitfires or Hurricanes. You may have worked for the NAAFI or Red Cross and served the airmen tea and sandwiches.

You may have diaries from the time, or written letters and taken photographs.

Or you may have been related in some way to one of the pilots. Whatever your involvement, male or female, it will help to paint a larger picture to celebrate what was Britain's "finest hour".
