I used to be the MMCO at NAS Memphis AIMD. Robert, as you already know, the A-4 and A-6 engine is the loudest engine ever to be produced, especially on a static test cell. Well, we had a backlog of A-4 engines to RFI. My Power Plant CPO wanted to work the weekend and get caught up, so, I let him. He ran one of those things up on the test cell during morning church services. Needless to say, I got a call from the Base Commanding Officer to shut that thing down. Guess he thought "God" did not enjoy the "Sound of Freedom".
