Visible crew/equipment: When the lone Huey helicopter comes to rescue Jack Ryan from a roof top, the reflection of the filming helicopter can be seen in its window.
Visible crew/equipment: When the Coast Guard Captain is looking through her binoculars at the yacht the camera switches to the binoculars' point of view to show the yacht in the distance. The front of another boat is visible just below the back of yacht, this couldn't be the front of the coast guard vessel so it would have to be whatever the film crew was using to get the binoculars' point of view of the yacht probably just a few feet away.
