And if they were underway, right at the edge of the reception area, that would explain the signal disappearing after 15 minutes, or 90 seconds.
Interestingly the AMSA "planned" search area for today (6/4) hasn't moved towards the 101e 25s location much if at all.
Not sure how far in advance they plan these areas.
