Mission 22 for iPhone

From Hunter Research and Technology:

Mission 22 is an addictive, action packed 2D shoot 'em up game with rich graphics, great sound effects, and a rocking background track. The app incorporates detailed visual touches like rendering of wingtip vortices, ailerons, and exhaust plumes (with afterburner shock cells), and includes five different terrain options. Hook up your headphones and enjoy panning stereo sound (headphones recommended but not required). Fast paced gameplay and an engaging interface will take you on a quest for better and better high scores! Your mission: Fly the F-22 Raptor deep into enemy territory to destroy as many enemy aircraft as possible. Stealth capabilities give you an advantage, but the sheer number of enemy aircraft make this a risky mission, and their long-range missiles will learn and adapt to your moves.
