imho, It's a lot easier to visualize if you use the Kruskal-Szekeres coordinates.

You have 100 ships lined up along the x-axis, all proceding forwards in time just as if we were in vanilla-flat-Minkowski spacetime with everybody at rest w.r.t. each other (i,e., if they have zero relative velocity, we can just pick that reference frame).

Every ship captain sees what's in their past light-cone, as usual

So if the ships are spaced 1 light-sec apart, then Captain 50 sees what's happening on the USS 49 and the USS 51 one second ago, the USS 48+52 two seconds ago, etc..

And the **only** difference the black hole makes is you're drawing this 45° line across the picture and that's the event horizon.
