70Sqn at Akrotiri had Argosys till at least 1972, the AOC of Near East Air Force had a VIP configured white over grey one operated by 70 and there were at least two other "standard" models in brown/sand camo which ran concurrently with 70's first Hercs IIRC.
Some Argosys (and Hercs) were adorned with large Red Crosses for ops to evac Jordanian Army wounded from Jordon to Cyprus during Black September. I remember the crews saying the smell was so bad (some wounded had gangrene) on some flights that they removed the cockpit overhead escape hatch
Later, 115Sqn operated them for nav-aid check/calibration, I think they were based at Benson.
115Sqn Whistling Tit at Wittering about 1974-5
