People on the Boro 15

. . . well it’s actually  on the Bay, San Juan Bay.  Coming upon this . . . I first thought an accident had occurred.

Note the two objects–helmeted heads–bobbing on the water in lower left.

Then a basket exits and lowers,

half a minute later it’s returning to the aircraft,

fifteen seconds later,

three minutes later,

and a minute later.

These vessels slowly left the scene.  My conclusion . . . a drill.

But I’m not sure.
