Airfix Shackleton AEW.2
The Mk 4 was 'phased' out of service in 67/68, and were only used (AFAIK) by MOTU for training and Farnborough/Boscombe for trials and photography; they had long gone by the time 8 Sqn formed (although there was one on the fire dump at Kinloss, whose wing tip was used to replace an AEW one that had a slight mishap whilst taxying!). The tail lookout was manned to give an accurate (depending on the crew member) call of the fall of bombs or other ordnance leaving the bomb bay. Of note pilot bombing, using 2 x eight and a half pound break-up bombs, was flown at 100ft and 160kts, aiming to straddle a towed target simulating a periscope/snort from a submarine - the ideal call from the rear being '50/50 zero line'.
