I know this is probably a stupid question, but in the weapons.tbl it says in the comment for missile trails that trails cannot be set if exhaust is set. What is exhaust? Is it something that :V: never used?

Most probably, as all missiles have trails and none of them have exhaust.

$Exhaust:                           YES
Where would this go? Or would it be like this)
$Flags:           ( "Exhaust" )

I think Exhaust was an early FS1 thing that did what $Trail now does and predates it by quite a bit. There is, as far as I can tell, no "Exhaust" related code other then the $Trail stuff, so the code was probably removed from the source a long time ago. (Well, except for the #define of WEAPON_EXHAUST_DELTA_TIME in weapons.h, which apparently is not used anywhere.)
