The 'posed' photo (note u/c was up) over Victoria Falls was 33 Sqn XW204 and was taken in 1981(I think) when the Sqn went out to Rhodesia for the Ceasefire Monitoring Force.
We did a similar pose a couple of days later. Hovering in the spray gave one a hollow stomach I can tell you!!
By the way, does anyone know what the Ceasefire Monitoring Force medal is worth these days?
