Maverick, don't you have all B5 seasons on DVD? Just open up B5 S2 season premiere "Points of Departure". When the Trigatti arrives to pick a fight with B5, it launches fighters and you can clearly see them arriving from a recess at the extreme nose of the War Wruiser. Another example would be in S1 "And The Sky Full of Stars" (as previously mentioned), when Sinclair's fighter is pulled into the Minbari Cruiser after being disabled. It may also be in ITB. I'll take a look.
OK, in ITB, they don't actually show a bay entrance there, but that's where Sinclair's fighter was brought in, so there must be some kind of bay, even if its covered by a door of some kind. I've uploaded a couple of shots of the front of a Sharlin from ITB, onto the project's FTP in the Reference folder, called MinbariScreenies.rar. Its also got shots of the atmospheric freighter/transport seen once in that movie as well. Unfortunately, the images were VERY dark, so I had to jack up the contrast to get make the profile visible. Most shots of it are from underneath, but there are a couple from the front and rear (rear one is very blurry as a result of the crop, zoom and contrast, it could look like anything to the untrained eye).
