really? hmm...while it may not work for player ships, how about this: have a freighter dock with a special container. this container would be mounted with a thruster (like a boost unit) which would activate under a SEXP (I'm sure there's one for this situation). with the combined thrust of both the container and the freighter, speed would be dramatically increased. however, the only flaws I can see are if the container AI would disallow it, and if containers are allowed to move while being held in place by a freighter. just a thought. (I also realize I may be repeating myself and that Venom may have already answered this question. if this is the case, I apologize.)
