Thank you for reminding me of that mod oxenos - of course you also forgot to mention that it drained into the bomb bay! After ITCZ transits we had to ensure the groundcrew (and occasional senior officer) stood well clear when we opened the bomb doors after landing. The flood we released was known to wash small aircraft away.
Re length of service - I think the 60+ MR2s started Sqn life in 1952, and at least 2 were still flying on 8 when I left in 1976, whereas the 12 AEW2 only started arriving in April 1972 (our first AEW flight was 20 Apr) and the last 6 fiinished in '91.
