At the end of the day, there was a NATO taskforce out there, and the AGI had slipped out of force coverage. No big deal and nothing unusual.
Yes, I understand that, but I did not understand the failure in the program to ponder the alternative scenario, that disappearing contacts tend to be submersibles. Much more exciting too!
