Are you Stealth?



From Wikipedia:

Stealth aircraft are aircraft that use stealth technology to avoid detection by employing a combination of features to interfere with radar as well as reduce visibility in the infrared, visual, audio, and radio frequency (RF) spectrum.   It is accomplished by using a complex design philosophy to reduce the ability of an opponent's sensors to detect, track, or attack the stealth aircraft.

From Daniel:

To avoid detection when doing something that you should not do, first DON'T DO IT.  However, if you must, employ a combination of actions such as not standing at the entrance when smoking or throwing your butts on the ground.  If you smoke in your car, put the butts in the ash tray in you car.
