The Mig-21 Bison, a simple but extremely lethal aircraft. The stand out feature of this aircraft is the under belly, twin-barrel, 50mm explosive slug, cannons. This is an absolute battleship killing machine. Other features included are After-burners(Throttle >95%), Countermeasures, Air-brakes, Brake Parachute(AG-1) and manualy adjustable inlet cone (it's a visual treat, just to mimic the original aircraft). To extended the inlet cone, use AG-2 and push the VTOL stick up and watch the inlet cone extend forward. In reality, it serves an important purpose, to deflect the super sonic air away from the aircraft and only let the sub sonic air into the jet engine, it is better explained on Wiki. Challenge - Try to take out all three ships(1 Aircraft-carrier and 2 Destroyers) in one attacking dive and take no damage.
