well, I would have the transport escort/attack in the masa system over the space lab. But I guess it could go either way. Realistically, though, why would confed need a borderworlds spacelab in the first place? It certainly isn't for developing the flashpak, and work on the genselect weapon seemed to be happening in axius.
Yes, in some ways it makes sense given what we have to work with to use the space lab mission but I preffer how the transport mission makes Confed seem like aggressors. and then Having catscratches "is that how wars start" conversation after is a nice touch.
Hmmm, what if after recovering the spacelab, Paulsen sends Blair message to destroy the convoy (simply dubbing over the mission briefing and showing the navigation demo in the communication box). Then all he has to do is destroy the convoy and both missions are completed.
On second thoughts, perhaps the Spacelab isn't needed that much, since the only time it is referenced is right at the end of the movie, the audience has probably forgotten about the Spacelab then anyway. Also the convoy mission is shorter, with the Spacelab they have to wait for the shuttle to dock and gain control.
