unless we were a human pilot in it.
Obviously. The only instance where this would be applicable is when starbuck "hotwires" her raider in the aforementioned episode. To pull it off, you'd have to actually play as Starbuck (unless we fanwank an instance when it happens again, but frankly this happening twice seems like too much of a stretch), we'd have to put in an enormous amount of work into creating not just the raider interior with all the guts and gore, but also the planet surface you take off from. After that, the mission would basically be to avoid Apollo's fire until you land on Galactica.
In short, it would be an incredible amount of work to pull off something that offers minimal gameplay value - don't expect it to happen unless someone mods it in on his own.
What about a cockpit for the heavy raider? We know they had skinjob pilots from time to time.
That, on the other hand, is possible, but it won't happen in R1. Heavy raider can also fly on it's own just like a regular raider, and doing cockpits is a lot of work - so for starters you'll just have to imagine that you *are* the heavy raider when flying it in multiplayer
