They said it's from Arizona

Context: in 1980 Indonesia wanted to buy ex-Israeli A-4 Skyhawk, but Indonesia didn't have formal diplomatic relationship with Israel so the purchase was conducted discreetly. This involves sending pilots and maintainers to Israel to learn how to fly and maintain A-4. The whole thing was called Operation Alpha

Indonesian Air Force never officially acknowledge this. And the whole thing was unveiled in a book written by Air Vice-Marshal (Ret) Djoko Poerwoko, one of the pilot sent to Israel.

Arizona also what the pilots refers to the base where they're trained, it was rumoured to be somewhere near Eilat. The pilots also after completing their training were brought to United States and told to take photos of America. They also take A-4 training at MCAS Yuma

Indonesian' Military and Police force may do little bit of trolling so their citizen won't be triggered by their actions
