What surprises me is that they did not setup a fully functional rig, they have 400 737 parked, and could have used one as a lab rig for the development of the SW, is that something difficult to do?
That would only handle the first 5 seconds or so of the software operation. As soon as any mechanical system was required you need a plane that is ready to be flown, as in fueled and generators and engines running. Otherwise it is stuck like a non-running car turned to the Run position, but not started, and is just an idiot light check. I think the risk of a ready to fly with engines-running plane in a parking lot is more of a problem.
