621andy,
I can't see the Spit - the Lat/Long you gave is the same as the one in your 0941Z post for the heli base.
Those Su7s at RGN - it's been a long time since I had to do a/c recce, but might they be Chinese-built F8s? A bit like a pointy-nose Mig19 Farmer, if my sad-spotter memory doesn't let me down.
Interesting part of the world you inhabit...
