I just watched "Movements Of Fire And Shadow" (season 5, ep. 17 of Babylon 5). At 32:38, the Centauri ships attacked Delenn's White Star.
It was previously stated that battles in hyperspace are disastrous for both sides (correct me if this is not the exact statement).
Nothing dangerous seems to happen to the Centauri ships. Why? Is it because they were ships without any crew and any fear (piloted by Shadow "brains")?
Delenn's ship got only usual damage, nothing special because of attack-in-hyperspace. Are such battles dangerous only due to drift-in-hyperspace? It seems to contradict to "disastrous for both sides" words.
Also, earlier in this episode, Star Furies attack a Centauri ship without crew. One Fury pilot dies, and two are wounded. Why? Is it because of the explosion during the exit from hyperspace?
In previous episodes, pilots also were not afraid to attack in hyperspace, as if it's rarely disastrous for both sides.
Is there any canon explanation of why hyperspace battles are dangerous, and why pilots in season 5 are apparently not afraid of attacking in hyperspace?
EDIT
In the episode 18 "The Fall Of Centauri Prime", Delenn's ship is lost in hyperspace and she uses firing to send signal while pushing her ship away. Probably, this "pushing back" is strengthened by hyperspace... or not.
