Ahem.....Your Physics and Logic are not welcome in a Fantasy IP where there is FIRE AND SOUND IN SPACE!
But there's fire and sound in Star Trek.... That's Sci Fi! :P
In reply to the poster a few posts above ^^
Space combat: You're completely correct the space combat in SW is far more suited to atmospheric flight. I think one of the few Sci Fi's to get what space combat would like right would be the re-imagined BSG.
