As Ken implied the monthly tasking was but a first 'draft' in respect of the actual flying done as extra tasking would appear throughout the month. The AT squadrons had very little control over their own tasking most of which was generated by external agencies. We were always below establishment but the tasking took no account of that inconvenient fact. Courses, leave, injuries etc all had an impact on personnel availability to carry out the tasking. It was always a juggling act !
