Thoughts behind my AR.
Most people tend to build things in similar fashions or at least try not to re-engineer the solution every time if they can help it. Things may have subtle differences, but on the whole structures of the same class should be similar. Therefore, AR would be high.
Are the emergency beacons still going off? Probably not, the computer system likely would have shut them down once all personnel was off station or after a period of time to conserve power in case they tried to access it again. Therefore low, but still worth a shot.
