In this blog of diary entries that will be posted daily as a day-by-day account of the Battle of Britain as it was seen at the time through the eyes of a young pilot, John Bisdee of No. 609 (West Riding) Squadron, Auxiliary Air Force. He kept a diary from the outbreak of war into 1941, recording not only his training and subsequent front-line flying, but also his off-duty life. We have transcribed his handwritten entries, and added notes to explain the RAF jargon and abbreviations that he used, and also to give extra information about the people and events described.
