Dunno, it just so happened I was exactly in the place where the Colossus was warping out, probably 6-8 kilometers from the warphole. Then I was too clumsy to avoid it before futilely frantically diving, diving, diving, and hitting my burners.
Which reminds me, that was one of the missions were you could actually command capital ships to do your bidding. Honestly, it's always fun to get capships kill other ships for you. I recall commanding the monitor to fend off an invading Aeolus (forgot the name), then in an instant, it did a mad turn and quickly decimated said cruiser.
