After flying into the Bermuda triangle you get teleported into another world where evil aliens plan to take over earth. You get a jetpack that allows you to switch between on-foot and air combat and it also makes it possible to fly up and take over the enemy flyers in the air. Flying them is fun but stealing them is not as the hand of Capcom has added quick-time-events all over the place. Game feels half completed in some areas and that seen mostly in the story that skip over some major events.
