Oh, so they *don't need the Pratt and Whitney F135 parts so they can use their F35s?
Former Israeli nat security advisor told Euronews that Israel is independent from the US - they use “only F15, F16 yes, but rather than that, we are independent”. He says EU is irrelevant and “they’ll come to their senses once they experience terror on their streets and realize we are the good guys”

Every f135 engine comes out of a factory in Connecticut. All the parts are made in America and Canada. You need to overhaul the whole engine after a certain number of flight hours. There is no dual sourcing these things

First time with the Holga Wide 120 pinhole camera. Given the quality of the camera I did not have high expectations but I was really surprised. These two were the best from 2 rolls of Kentmere 400. Exposures were from 2.5 - 8.1 seconds. f135 aperture. (Loved the accidental double exposure).

XA100 is a next-generation Adaptive Cycle jet engine in development at General Electric.
It's a "three stream" 200 kN-class turbofan with CMC turbines that can adjust its bypass ratio for better cooling, thrust or efficiency. It promises +35% range over the current F-35 with F135.
