We're all drooling to see one of your newest videos/in-flight pics with this... !
I have this AB ring too on my L-39, but the effect is not fully the same, your viewing angle for the light is unbelievable and VERY intense, even more because it is installed inside the tailcone of the F-16.
Your pics were taken with a running turbine, right ? Didn't I see you holding a bottle of Norvegian liquor on the first photo ??? Is it that cold there now ??
