Mas 2.7 -

Over the next hour, she used MAS 2.7 three more times—first to decide to keep the ship stationary (preserve fuel and position), then to authorize a narrowband ping to the drones (low risk, high information gain), and finally to communicate a revised plan to Guam before they issued an unnecessary search-and-rescue order.

It wasn't ordinary fog. It was a data fog .

If any drone transmits a single valid temperature reading, my assumption of "total sensor failure" is wrong. If the fog lifts by 200 meters of visibility, I can revert to standard navigation. mas 2.7

Within eight minutes, the sonobuoy picked up the rhythmic pulse of drone propellers—all still running, all still in formation. No collision, no loss of power. The magnetometer glitch hypothesis became stronger. Then, at minute 12, one drone's temperature sensor flickered back online. Not a full fix. But a signal .

Order all drones to ascend to 50 meters below surface (shallow enough for possible radio recovery, deep enough to avoid surface debris). Simultaneously, deploy a single passive sonobuoy to listen for drone propellers. Do not recall the ship's launch boat. Do not commit to a new course. Over the next hour, she used MAS 2

She issued the orders.

Captain Elena Vasquez had commanded the research vessel Argo for twelve years. She knew its every creak, every lag in the port engine, every quirk of its sonar. But she had never faced a fog like this. If any drone transmits a single valid temperature

Julian (first officer), the lead geologist (because she's worried about mission data), and engineering (because they suspect the software patch). Not the whole crew—too much noise. Not Guam yet—too far away to help in 10 minutes.
