Clean the airfield by dropping bombs.
You had come back from a mission with your plane. The fuel was running out
and the altitude is decreasing from round to round. On the airfield you can see
lots of barrels. The plane cannot landing while the airfield is not clear!
But lucky thing how you have some bombs in the plane. These are very useful items
for disappearing barrels.
