Times are shown in the format hh:mm

Dates are shown in the format dd.mm.yy and also in Army format YYMMDD to enable sorting as a text field.

Caution should be exercised if converting dates to a spreadsheet format as dd.mm.14 may be interpreted as dd/mm/2014 and not dd/mm/1914

Entries in square brackets '[...]' are my comments and do not appear in the original document.

If loading files into a spreadsheet I recommend specifying all fields as 'text'.

Note that references to 'Raf' refer to the Royal Aircraft Factory and not Royal Air Force, and 'plane' refers to an aircraft wing and not an aeroplane.

Where two names are given the first named is the pilot and second the observer or aerial gunner. If only one name is given it should be assumed to be the pilot unless appended by (obs) for observer or (AG) for aerial gunner.
