Cloaking Emissions

I've run into a slight conundrum while implementing full ship cloaking. And that is.. how do you hide your emissions? Redirecting/bending electromagnetic waves around a body or surface is one thing, but when your drive systems must propel a particle or gas, how do you hide trail? So for now, realistic, crappy cloaking, until the United States develops some propellentless drive system.

New:
US Fighter
Missiles
Cloaking
Basic Context Menus
Revamped UI
And renamed Engine to LycanEngine (it was Ace's idea)
