WTF....Thats awesome how did you do it?

Take any aircraft you like and add a [smokesystem] to the .cfg file, if it doesn't have one, then add the line: smoke.X= YYY.YYY, 0.00, 0.00, fx_fireworkZZ.
"X" is the next available "smoke" line
"YYY.YY" is the distance in front of the aircraft, and the faster the aircraft, the farther out in front you want to place the firework effect, keeping in mind the time it takes you to fly through the effect. To get a nice "tunnel" effect, just hold the "I" key down for three or four "bursts".
