As has been stated previously, large starships, such as carrier ships, have enough energy resources to create their *own* entry into hyperspace, their own jump points. The jump gates are mainly used for smaller ships, or big ships that want to conserve energy. Thus, the Vorlons used the jump gate in order to detach their smaller ships *before* entering B5's space, so that they could go in on the attack immediately, rather than having to separate from the mothership after arriving via a separate jump point. Since they were expecting some sort of Vorlon craft, no one thought much of it; the frequency matched with the ambassador's craft. It's only when everything came out that they saw it was more than it seemed. One other item: a jump gate isn't like a light bulb, you can't just switch it off suddenly. There are massive reactions and energy flows going on in there, and it takes a fairly long period of time to shut one down without blowing the thing to kingdom come. Also, you endanger any other craft heading for it or midway through a jump. During the Earth/Minbari war, EA jump gates were encoded to reject any ship coming in on the wrong ID frequency, which helped to slow down misuse of certain gates, though the codes would eventually get cracked, which meant they had to be changed on a fairly regular basis. In "Midnight on the Firing Line," you will see how a carrier-size ship makes its own jump point. jms |
