This trick requires the Jewel Satellite. At the beggining of Hornet Man's stage, 
move to the right until you reach the first ladder. Without destroying the 
potted plant robots, activate the shield and stand on the second platform in 
between both the robots. If you remain standing there, the missiles will be 
destroyed and the screws will automatically land on Megaman. This also increase 
your kill count for the "Destroyer" achievement.
