A larger volume of work fell on the R.A.F. side than on the Army because most of the Army tasks were concerned with long-term policy, whereas the Marshalling Yards, Airfields and Bomb Damage sorties all required an immediate report; it was not until Night Photography (where the tasks were primarily for the Army and of a tactical nature) was in full swing that John's Section had its most strenuous periods.     As a result of exercise "EAGLE" it was agreed to add another squadron to 34 Wing to carry out night visual reconnaissance and low-level photography. There was much argument as to the type of aircraft which would be most suitable for this work, but eventually the Wellington was selected and, on 5th May, 69 Squadron arrived at Northolt. This squadron, which came from Malta, was commanded by Martin Channon and arrived at Northolt in large numbers but with no equipment. This influx at such a late stage in the proceedings needed a great effort from everybody; the squadron had to be equipped with aircraft which would need much modification; the ground staff had to learn all the details of a new aircraft; the crews had to be converted to fly them and to be taught the technicalities of photography and reconnaissance in this theatre.
