Actually, the Empyrean Age expands on the question about crew. On many ships, the crew and passengers have to be secured during warps, since apparently, violating several laws of physics isn't comfortable. So, for example, in TEA the crew of the Retford (flying piece of old junk) were suffering from warp sickness after evading the Blood Raiders. Of course, some ships are just more advanced, and do not need the same measures. After being picked up by Lord Victor, the Retford crew did notice when the Purifier warped, but did not feel any ill effects. (Covert ops have one of the most advanced warp drives in existence, and I bet the Sarum ship was brand new. Possibly shiny, too, if it was not cloaked.)
