Seriously it is an intentional replayability feature... that nobody has noticed until now.
i noticed

but i didn't know that no one else knew about it.
the whitestar doesn't just collide with each other at the beginning. They behave like small fighters and ram into each other all the time.
The fact is, even the enemy fighters ram others all the time. I don't remember this in Freespace...
But it is very fun playing the missions again.
I personally feel that the beam weapon should be secondary weapon on the Whitestar. The 2 particle weapons are rather slow to be efficient, and with the beam turned on the weapon enegy drains too quickly. But then I guess it is not as easy as it sounds. Anyway, the White Star probably isn't suppose to dog fight small fighters anyway.
In the second mission you can just destroy everything on screen with a White Star, except the Madusa, since otherwise the stroy can't continue

I like to replay the missions with a PSI Thunderbolt with White Star wingmen. Also, I love the Centari fighter. It is not as vunerable is it seemed when the computer AI is controlling it. The canon speed is excerlent and damage level is pretty impressive. It is fast and manuverable (well, it doesn't strafe like the Starfuries. But during dog fight, Strafing is too slow to be of any use (except for the AI..... they use it and the response seems pretty impressive.
By the way, cheat or no cheat, you could order the G.O.D Sat. in the Spanish Inquisition mission, and it is awesome.
