Bombardment

Shock, horror, the world has been invaded by aliens. They are largely inactive little blighters who are definitely in need of some killing. You have a load of bombs and a handy fighter jet. It is you who will do the killing. You can choose where the bombs will be launched from, and at what angle they will fly, and which type of bomb you are using. You just have to make sure the aliens are blown up, or end up off the screen.
