OK, now I’m baffled.
I have no idea where they’re taking the plane. My first guess would have been Blount Island. But, they’re heading the wrong way. They’re moving the plane up river (south, yes I know that can be confusing) to Green Cove Springs. Which doesn’t have anything like commercial dock/port infrastructure.
