When Garibaldi and Sinclair leave Babylon 5, they are at the head of a small fleet of rescue ships. A little later, they are shown to be flying alone. And in the next scene, they are again leading a fleet.
There is a scene at the 23:49 mark where Lt. Cmdr. Ivanova is looking out of the window. The leather detailing on her tunic is on the wrong side.
A film crew member can be seen sitting on a pile of equipment as the Babylon 4 crew are evacuating the station.
When Sinclair gets blasted into crates, while Garibaldi is helping him up, on the right side of the screen can be seen a film crew member sitting up on some boxes watching. He's wearing a red and white shirt and a ball cap.
