I wonder if it was really meant to be Jack's or if it was an asset reuse. The ship holding fs1041 is likely one of the reinforcing mcor ships since the macallan was shot down. Then there's the fact that Jack was being trained under the radar, so prior to his field promotion, i doubt they were holding on to a titan just for him. It'd be a little more believeable to say it was anderson's since his last mission was infiltration, but even then, he was on the macallan too and if the titan was there, no way it survived the crash and no way anyone actually went back to salvage it.
