I have always had an appreciation for aviation.  I prefer the fighter jets of course, who wouldn't.  I would say my favorite jet would be the F22 A Raptor.  This thing is absolutely amazing and it truly dominates the skies.  It was designed to dominate the sky, however it also is capable of handling ground attacks, electronic warfare, and signal intelligence roles as well.  The combination of speed, stealth, agility, precision and situational awareness make it the best overall fighter jet today!
