After rewatching the GROPOS, I'm pretty sure that those Large Transports that arrived with the Nova are the same ones inside the hangar, which means there is scaling problem/CGI Glitch as PSI-KILLER mentioned
The ones seen entering the B5 are different though....
Anyway, thanks for the hint Prophet, I really need to rewatch the Season 5

Having two versions would definetely be good idea
Now we only need class names 'n stuff, I assume there is no official info available ?
Little OT, maybe, but I couldn't help but notice. The Valkyrie Gunships seen in GROPOS (3 of them) are also seen in the "severed dreams", as the Clark's fleet is moving trough hyperspace !
Funny little things they are, these CGI-screenfillers do not take part in any of the action outside the station, nor do they appear in any other scenes, talk about the cgi-error...these gunships are supposed to operate/fight in atmosphere only.
Was Clark planning to invade epsilon eridani 3 in the process, if anyone tried to escape there ?

Has anybody else noticed that ?
